Role of ATP
1) At what point during cellular respiration do the electrons have the most energy? At what point do they have the least energy. (You should describe the molecule that electrons are part of at each of these points)
2) When electrons lose energy, that energy goes somewhere. Where does that energy go to immediately, and where is that energy at the end of cellular respiration.
3) Give an example of potential energy in Cellular Respiration. Give an example of kinetic energy in cellular respiration.
There are a few things that go along with eukaryotes which are, plants, fungi and protozoa. The net ATP yield for eukaryotic cells are 2 ATP moving through membranes, however, in other words only have 36 ATP.
How many chemical reactions (steps) are involved? Briefly describe them.

How does the ATP-ADP cycle provide energy for the cell? 3 Why is the ATP-ADP cycle important to living things?arrow_forwardFirst, you should map out all of the biochemical stages and processes in cellular respiration and photosynthesis. This means all of the stages are unpacked in-depth (light-dark Calvin Krebs glycolysis) into stages, their inputs (reactants), outputs (Products), and interdependent molecules (connected molecules). Add more detail to the mind map below about cellular respiration and photosynthesis. (Also added an extra image of what the level of detail should be.)arrow_forwardFor each of the statements below, indicate whether they are true or false and then in detail explain why the false statements are incorrect, making reference to the relevant cell processes and/or molecules. A. In cellular respiration the ETC transfers electrons via redox reactions whereas in photosynthesis the ETC transfers electrons using light. B. In cellular respiration the ETC creates a proton gradient with the higher concentration on the outer side of the inner membrane whereas in photosynthesis the ETC creates a proton gradient with the higher concentration on the inner side of the thylakoid membrane. C. In cellular respiration the ETC gradient is used to power ATP production by oxidative phosphorylation whereas in photosynthesis the ETC gradient is used to power ATP production by substrate level phosphorylation.arrow_forward
