The mitochondria has been known as the powerhouse of the cell. What does that even mean? Well, what it means that the mitochondria does all of the cell energy conversion. It takes nutrients from the cell and transforms it into viable ATP. ATP, molecule adenosine triphosphate, is the energy that cells can use. The process in turning nutrients into ATP is called ATP Synthase. The first part of ATP synthase is an ending of cellular respiration. The mitochondria plays a small but large role in the cell

Assignment on how one sugar molecule goes through (1) Glycolysis, (2) The Krebs Cycle, and (3) The Electron Transport Chain to make ATP Betsy Eapen Odessa College, Department of Microbiology We got most of the energy from the food we eat to function our daily activity. One of the important ways for a cell to get energy is from cellular respiration, a catabolic process, the breakdown of molecules into smaller units for the production of ATP, and the final electron acceptor comes from

absorbed by chlorophyll drives transfer of electrons and hydrogen ions from H2O to electron acceptor NADP+, which is reduced to NADPH and temporarily stores electrons O2 is released when H2O is split ATP is formed during light reactions, using chemiosmosis in photophosphorylation In Calvin cycle, CO2 is incorporated into existing organic compounds by carbon fixation, and these compounds are then reduced to form carbohydrate NADPH and ATP from light reactions supply reducing power and chemical energy

sources, for an example plant life receives its energy source from the Sun. All other forms of life receive energy through cellular respiration. Cellular respiration happens in three stages; Glycolysis, The Krebs Cycle, Electron transport chain and chemiosmosis. The cellular respiration process can be aerobic or anaerobic. In order for the human body to function it requires energy, the body’s energy source comes from the food we eat on a daily bases. We consume carbohydrates, fats, and proteins that

Hydrogen ion gradients play a role in cellular respiration in the mitochondria an in photosynthesis in the chloroplasts (Wikipedia, n.d.). During cellular respiration, it is important to know, that hydrogen ions are pumped out of the matrix or out of the cytoplasm and that this creates a concentration gradient, which forces hydrogen ions back into the matrix or cytoplasm and forces ATP synthase into action. Therefore, hydrogen ions move across a semipermeable membrane to an electrochemical gradient

Introduction Cells are the basic units of life and their processes are vital to the functioning of all organism. The reactions of photosynthesis and cellular respiration are complimentary and are also the most important pathways on the Earth. Photosynthesis is a process that converts carbon dioxide into organic compounds in presence of sunlight. Cellular respiration is the set of metabolic reactions that take in cells of living organisms that convert nutrients like sugar into energy , which is

Plants utilize chloroplasts to perform photosynthesis to produce glucose. Photosynthesis consists of two stages called light reactions and the Calvin cycle. Within the chloroplast, the thylakoid is the site of light reactions. The thylakoid is capable of absorbing light energy and transforming it to chemical energy in the form of ATP and NADPH which will later be used in the Calvin cycle. Pigments located inside the thylakoid allows for the absorption of visible light (Campbell, pg. 191). There are

phosphorylation, an electron transport chain works in conjunction with chemiosmosis to create energy molecules named adenosine triphosphate (ATP) using oxygen and simple sugars. In the electron transport chain, an electrochemical gradient is formed by the chemical gradient from the inside to the outside of a mitochondrion counteracting with the electrical gradient from the outside to the inside of the mitochondrion. During chemiosmosis, the energy stored in the gradient is used to make ATP. In addition

Oxygen is the byproduct of a water molecule breaking down in the beginning of photosynthesis to supply photosystem II with electrons. There is no role of oxygen in photosynthesis. Oxygen is used as the terminal electron acceptor during respiration. Chemiosmosis is movement of ions across a membrane, down their electrochemical gradient. It relates to ATP by the movement of hydrogen ions across a membrane during cellular respiration or photosynthesis. ATP respiration breaks down complex molecules to release

exergonic fall of the electrons to a lower energy level provides energy for the synthesis of ATP (adenosine triphosphate). As electrons pass through the cytochrome complex, the pumping of protons builds a protein gradient that is subsequently used in chemiosmosis. Meanwhile, light energy was transferred via light-harvesting complex pigments to the Photosystem I reaction-center complex, exciting an electron in the Photosystem I chlorophyll a pair. The photoexcited electron was then transferred to Photosystem
