Slide #1
Hello, my name is Audrey and welcome to my presentation on the chemistry of photosynthesis and cellular respiration.
Slide #2
To begin, both systems are considered interdependent, which means that one is dependent on the other. You can’t have photosynthesis without cellular respiration and vice versa. Basically, they are two sides to the same coin
Slide #3
The first side of the proverbial coin is photosynthesis. Photosynthesis is an endergonic reaction, meaning that plants absorb light energy, in order to turn carbon dioxide and water into chemical energy.
Slide #4
The very word, photo “synthesis” gives away what kind of reaction it is…a synthesis reaction. In this case, you have two products ( ) in the presence of light energy

Once our digestive system has done its thing, breaking larger down into smaller particles, the resulting [products] are carried to our cells by our circulatory system to our tiny cells where cellular respiration happens.
Slide #8
Unlike photosynthesis, cellular respiration is an exergonic reaction where energy is released, rather than absorbed. This released energy is called ATP, the energy currency of the cell.
Slide #9
Also, unlike photosynthesis, cellular respiration is known as a decomposition reaction. During this reaction, the exergonic release of energy is produced by breaking glucose down into smaller ATP molecules, water and carbon dioxide which is released into the air, for use by plants, every time we exhale
Slide #10
Like Photosynthesis, cellular respiration is also a redox reaction where glucose loses electrons and hydrogen atoms to produce carbon dioxide causing the glucose to become oxidized. At the same time, oxygen gains electrons and hydrogen atoms, reducing it to water.

Both photosynthesis and cellular respiration are the main pathways of energy transportation in organisms. However, the reactants and the products are exact opposites in photosynthesis and in cellular respiration.
The Cellular respiration and photosynthesis form a critical cycle of energy and matter that supports the continued existence of life on earth. Describe the stages of cellular respiration and photosynthesis and their interaction and interdependence including raw materials, products, and amount of ATP or glucose produced during each phase. How is each linked to specific organelles within the eukaryotic cell? What has been the importance and significance of these processes and their cyclic interaction to the evolution and diversity of life?
Cellular respiration is bioenergetic process, meaning that it is governed by enzyme activity. Referring to what was previously learned about enzymes, it is known that enzyme-substrate reactions can
Cellular respiration is a redox reaction that combines glucose & oxygen to produce carbon dioxide, water, and energy.
Cellular respiration is the process by which cells get their energy in the form of ATP. There are two types of cellular respiration, aerobic and anaerobic. Aerobic respiration is more efficient and can be used in the presence of oxygen. Aerobic respiration, or cell respiration using oxygen, uses the end product of glycolysis in the TCA cycle to produce more energy currency in the form of ATP than can be obtained from an anaerobic pathway.
In cellular respiration, the oxidation of glucose is carried out in a controlled series of reactions. At each step or reaction in the sequence, a small amount of the total energy is released. Some of this energy is lost as heat. The rest is converted to other forms that can be used by the cell to drive or fuel coupled endergonic reactions or to make ATP.
To be able to carry on metabolic processes in the cell, cells need energy. The cells can obtain their energy in different ways but the most efficient way of harvesting stored food in the cell is through cellular respiration. Cellular respiration is a catabolic pathway, which breaks down large molecules to smaller molecules, produces an energy rich molecule known as ATP (Adenosine Triphosphate) and a waste product that is released as CO2.
Organisms are complex and use energy to function, grow, and reproduce. Organisms get this energy from photosynthesis and cellular respiration. Photosynthesis is the process by which plants harness sunlight to make glucose from carbon dioxide and water1. Photosynthesis provides glucose for cellular respiration. Glucose is the reactant for cellular respiration. Cellular respiration has complex stages, where the glucose molecule is slowly broken down. The formula for cellular respiration is C6H12O6 + 6O2 ⇢ 6CO2 + 6H2O + energy.
Every living thing needs cellular respiration to survive. Cellular respiration is the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen. This process happens through three distinct operations which are glycolysis, the Krebs cycle, and the electron transport chain. Throughout these cycles, our bodies turn oxygen and glucose into carbon dioxide, water, and energy. Although this system seems simple enough, cellular respiration can not take place in just one step because all of the energy from glucose would be released at once, most of it being lost in the form of light and heat. All this plays a very important role in our lives and without it, organisms would cease to exist.
Cellular respiration is a process that happens in all living eukaryotic cells. What cellular respiration does is turn food often carbohydrates into energy for our bodies. Cellular respiration starts with a carbohydrates sugar called glucose. What it does is alter and break down the six carbon molecule glucose and altering it creating two three carbon molecules called pyruvic acids in an anaerobic process called glycolosis (Cellular respiration). What this process does is create two ATP molecules which are basically molecules which provide energy to run all cellular processes in our bodies (king). However, from here in the process can turn aerobic, meaning using oxygen if present or anaerobic meaning when oxygen is not present in a
If you expose a photosynthesizing plant to water that contains both radioactive H and radioactive O, in which of the products of photosynthesis will the radioactive H and O show up?
Photosynthesis and cellular respiration are both needed for life to exist; however, there are differences in the two process. Photosynthesis must have energy in order to create glucose and cellular respiration uses glucose to produce energy. Photosynthesis converts energy from sunlight, storing it for later to create glucose (Open Learning Initiative, 2013). Sugars are broken down and converted to energy during cellular respiration (Open Learning Initiative, 2013). Chloroplasts and chlorophyll are utilized to absorb energy during photosynthesis, but any living cell can be used for cellular respiration. During photosynthesis carbon dioxide and water are utilized to develop oxygen and during cellular respiration oxygen is used then carbon dioxide
All living organisms need the energy to perform the basic life functions. Cells use a process called cellular respiration to obtain the energy needed. In cellular respiration, cells convert energy molecules like starch or glucose into a cellular energy called Adenosine triphosphate(ATP). There are two types of cellular respiration which include: Aerobic and Anaerobic respiration. In aerobic respiration, cells will break down glucose to release a maximum amount of ATP this takes place in the presence of oxygen. Aerobic also produces carbon dioxide and water as waste products and it takes place in the mitochondria. on the other hand, anaerobic respiration, a metabolic process, also produces energy and uses glucose, but it releases less energy and does not require the
Cellular respiration is the group metabolic reactions that happen in the cell of living organism that creates adenosine triphosphate, ATP, from biochemical energy. The formula for cellular respiration is C6H12O6 +6O26CO2+6H2O+ATP. This formula means glucose and oxygen are turned into water,carbon dioxide and adenosine triphosphate (ATP) energy through chemical reactions. Cellular respiration occurs in all cells which allows them to grow. Raphanus raphanistrum subsp. Sativus seed, also known as radish seed, undergo cellular respiration because they are not yet able to perform photosynthesis, which is how plants create their energy. Hymenoptera formicidae,commonly known as ants, undergo cellular respiration to produce the energy they need to live.
Photosynthesis has a two-stage performance before plants produce the two products they are known to produce. These stages are Photosystem I and II. Photosystem II is dependant on light reactions for energy which causes the electrons to be react and be transferred to Photosystem II. The electrons are transported through the Photosystem II electron transport system, however some energy is used to drive ATP synthesis. Meanwhile, light is being absorbed by the Photosystem I, which causes the electrons to react. This process sends the electrons to the Photosystem I transport system where some energy is released as electrons travel through the electron transport system and is captured as NADPH. When this process is completed oxygen is released from the plant and glucose has been
