How are cell like a furnace?
How is the cell like a furnace? First stage of cellular respiration. Carries the high-energy electrons to the ETC, where they can be used to produce more ATP.
Why is comparing cellular respiration to a burning fire?
In cellular respiration, glycolysis is anaerobic. Why is comparing cellular respiration to a burning fire a poor analogy? A fire burns all of it’s potential energy, whereas cellular respiration stores is as ATP. In glycolysis, glucose is reduced.
How do cells burn oxygen?
Once the red blood cells return to the lungs, the “burnt” carbon dioxide is exhaled). What cellular component allows the combustion process to occur? (The energy station of the cells, called mitochondria, process oxygen to power the cells. As part of the combustion process, carbon dioxide is released.)
What is the cellular respiration reaction?
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products.
What are the 4 stages of cellular respiration and where do they occur?
The cellular respiration process includes four basic stages or steps: Glycolysis, which occurs in all organisms, prokaryotic and eukaryotic; the bridge reaction, which stets the stage for aerobic respiration; and the Krebs cycle and the electron transport chain, oxygen-dependent pathways that occur in sequence in the …
Why the number of ATP is not known exactly?
The total number of ATP is not known exactly and is due to variance in the degree of coupling between the flow of protons through the ATPase and electron transport. ATP – Adenosine triphosphate, the energy currency of the cell are organic compounds composed of the phosphate groups, adenine and sugar ribose.
How is 36 ATP formed?
As a result, between 1 and 2 ATP are generated from these NADH. In eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38, depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH.
How are 38 molecules of ATP produced in glycolysis?
This process occurs through the breakdown of one molecule of glucose. Here the ATP molecules first form in the cytoplasm through glycolysis and then it is moved to the inner mitochondrial membranes where it produces 36 ATP molecules. Thus, the total ATP molecules produced are 38. So, the correct answer is ‘2’.
How is ATP produced in a cell?
Most of the ATP in cells is produced by the enzyme ATP synthase, which converts ADP and phosphate to ATP. ATP synthase is located in the membrane of cellular structures called mitochondria; in plant cells, the enzyme also is found in chloroplasts. In eukaryotic cells the latter two processes occur within mitochondria.
How many ATP is produced in glycolysis?
2 ATP
Which has more energy ATP or Nadph?
The main difference between ATP and NADPH is that the hydrolysis of ATP releases energy whereas the oxidation of NADPH provides electrons. Furthermore, ATP serves as the main energy currency of the cell while NADPH serves as a coenzyme with the reducing power needed by the biochemical reactions.
Which step of photosynthesis produces the most ATP?
So, oxidative phosphorylation is the metabolic cycle that produces the most net ATP per glucose molecule.
How is ADP used in photosynthesis?
When a phosphate breaks off, through chemical reactions in a cell, energy is released which the plant uses for cellular processes. The lower energy Adenosine DiPhosphate (ADP) is then re-energized during photosynthesis as the phosphate group is re-attached, thus completing the cycle of ATP to ADP to ATP…
Is ADP light dependent?
In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. When these molecules release energy into the Calvin cycle, they each lose atoms to become the lower-energy molecules ADP and NADP+.
Where is ADP used in photosynthesis?
They require light, and their net effect is to convert water molecules into oxygen, while producing ATP molecules—from ADP and Pi—and NADPH molecules—via reduction of NADP+. ATP and NADPH are produced on the stroma side of the thylakoid membrane, where they can be used by the Calvin cycle.
