Where does the 1st stage of cellular respiration take place?

Where does the 1st stage of cellular respiration take place?

cytoplasm

Where in the cell does the first stage of cellular respiration take place quizlet?

Where does the first stage of respiration take place? In the cytoplasm of the cell.

What does cellular respiration need to occur?

Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water. …

Can photosynthesis occur without cellular respiration?

Without photosynthesis, there would be no sugar, without which there could be no cellular respiration. Both animal cells and plant cells depend on cellular respiration for their energy needs, because both animal cells and plant cells need ATP.

What is the location of ETC and Chemiosmosis in photosynthesis and cellular respiration?

The generation of ATP by chemiosmosis occurs in mitochondria and chloroplasts, as well as in most bacteria and archaea, an electron transport chain pumps H+ ions (protons) in the thylakoid spaces through thylakoid membranes to stroma (fluid).

Where is Chemiosmosis located?

Where does chemiosmosis occur? In eukaryotes, it occurs in the mitochondria during cellular respiration and in the chloroplasts during photosynthesis. Prokaryotes lack these organelles and therefore chemiosmosis will occur in their cell membrane.

What is the difference between Chemiosmosis and oxidative phosphorylation?

oxidative phosphorylation: A metabolic pathway that uses energy released by the oxidation of nutrients to produce adenosine triphosphate (ATP). chemiosmosis: The movement of ions across a selectively permeable membrane, down their electrochemical gradient.

Does Chemiosmosis require oxygen?

In chemiosmosis, the energy stored in the gradient is used to make ATP. If oxygen isn’t there to accept electrons (for instance, because a person is not breathing in enough oxygen), the electron transport chain will stop running, and ATP will no longer be produced by chemiosmosis.

What waste product is released during cellular respiration?

carbon dioxide

Where do proteins enter cellular respiration?

When proteins are used in the cellular respiration pathway, they are first broken down into individual amino acids. The amino group from each amino acid is removed (deaminated) and is converted into ammonia. In mammals, the liver synthesizes urea from two ammonia molecules and a carbon dioxide molecule.
