Compare And Contrast Eukaryotic And Photosynthesis

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.

Photosynthesis occurs each time the sun’s light reaches the lives of a plant. The chemical ingrediants for photosynthesis are carbon dioxide (CO2), a gas that passes from the air into a plant via tiny pores, and water (H20), which absorbed from the soil by the plant’s roots. Inside leaf cells, tiny structures called chloroplasts use light energy to rearrange the atoms of the ingrediants to produce sugars, most importantly glucose (C6H12O6) and other organic molecules. Chlorophyll gives the plant its green color (Simon, 02/2012, pp. 92-93). Chemical reactions transfers the sun’s light energy into the chemical bonds that hold energy-carrying molecules. The most common are

All living things ultimately depend on this process. The compounds plants make during photosynthesis provide nutrients and energy to organisms that consume plants. Organisms that consume the plant-eaters gain nutrients and energy from them, so both energy and materials are passed from organism to organism.

Photosynthesis is the procedure in which green plants use sunlight, carbon dioxide and water to make food and oxygen and cellular respiration is the process where cells use this food to

Photosynthesis envelopes everything we need to sustain life whether directly related or indirectly related. Biology involves a great responsibility for the safety and well-being of all inhabitants of the earth. Our daily lives and the comprehension of what it takes to keep the

Photosynthesis is essential to all living organism such as animals and plants. Photosynthesis is a process used by plants and other autotrophs to capture light energy and use it to power chemical reaction that converts carbon dioxide and water into oxygen, carbohydrates and water. (Textbook: Principles of Biology). The reactants and the products of photosynthesis are:

The second step is producing sugars with that energy, which is being stored. Pigments are these colorful chemical compounds that absorbs the light from the sun, which is then sent to the chloroplast. When the cells capture the energy some of that energy is used to make chlorophyll, which is a type of pigment which is green. It creates energy for the process of photosynthesis. Photosynthesis is very important for plants, but also for

The electron transport chain produces the most ATP (34). The reactants for cell respiration are glucose and oxygen; the products of cell respiration are, carbon dioxide, energy, and water, this is also shown in the chemical equation: C6H12O6 + 6 O2 --> 6 CO2 + 6

Photosynthesis is a process that uses water, sunlight, and carbon dioxide to make oxygen and glucose (sugar). The process is light energy is converted to chemical energy.The steps are that sunlight, water, and carbon dioxide goes inside the plant. Then the outputs are oxygen and glucose (sugar). Photosynthesis is needed to make energy. It also provides us the oxygen we need.

Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special way of using the ATP they produce. Photosynthesis is a process where plants harness the sunlight they receive and they produce carbohydrates, as well as oxygen for living things and other plants. Now the sunlight ultimately powers the process of

     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

Photosynthesis is an important process to living organisms because eliminates Carbon Dioxide and releases Oxygen by the use of a plant. Pigments are color molecules the absorb lights in different color wavelengths of light. The light that the pigments absorb turns into energy (Glucose) in the photosynthesis process. They are different types of pigments like Carotenoids, Anthocyans, Xanthophyll, and Chlorophyll which is the major light absorbing pigment in plants. The more pigments the more food for plants to eat. The pigments absorb energy from different color wavelengths and reflect another like plants which give the color green. The importance of light and pigments don’t only play important role in photosynthesis they also are important to maintain life.

     To metabolic pathways involved in photosynthesis are light reaction and dark reaction. The first stage of the photosynthetic system is the light-dependent reaction, which converts solar energy into chemical energy. Light absorbed by chlorophyll or other photosynthetic pigments is used to drive a transfer of electrons and hydrogen from water to and acceptor called NADP , reducing it to the form of NADPH by adding a pair of electrons and a single proton. The water or some other donor molecule is split in the process. The light reaction also generates ADP, a process called photophosphorylation. ATP is a versatile source of chemical energy used in most biological processes. The light reaction produces no carbohydrates such as sugars.

Cellular respiration occurs in both plant and animal cells. Both types of cells are very similar, containing similar organelles such as the mitochondria. The mitochondria is the site of cellular respiration, where glucose and oxygen can be used to produce ATP and carbon dioxide. In plant cells energy is created through the process of photosynthesis, the conversion of energy from the sun into chemical energy. Autotrophs are able to utilize photosynthesis to sustain themselves without consuming food to obtain energy. The site of photosynthesis takes place in the cell’s chloroplast (Citovsky, Lecture 20). A large, concentrated portion of chloroplast can be found within the plant’s mesophyll, the interior of a leaf. Photosynthesis is broken down into two stages: light reactions and the Calvin cycle. Through light reactions, solar energy can be converted into chemical energy (Campbell, pg. 189). In the Calvin cycle, usable energy in the form of sugars are synthesized from carbon dioxide.

Photosynthesis is a very complicated process. It is not as simple as plants need a little sunlight, water, and carbon dioxide, and viola oxygen is produced. There are many steps and processes that occur during photosynthesis which make it very complicated. Now the actual word photosynthesis in Greek means photo- “light”, and –synthesis “putting together”. This is the overall basic foundation that photosynthesis stands behind. Photosynthesis can only happen in plants and some algae, due to them having an organelle called chloroplast. Chloroplast has a pigment, which is called chlorophyll. Chlorophyll is a light absorbing pigment, which allows the plant to control solar energy and use it to distribute energy and food for the plant itself. Chloroplasts are usually located in the green tissue in the interior of the leaf called the mesophyll. A usual cell has around thirty to forty chloroplast. In the inner compartment there is a thick fluid called the stroma, with a system of interconnected membranous
