Question
This process is the main source of ATP (“A-T-P”) in eukaryotes. For 10 points each:
[10m] Identify this process, the final step of cellular respiration, which concludes with protons moving across a membrane through ATP synthase. It uses up molecules like NADH formed earlier in metabolic pathways.
ANSWER: electron transport chain [accept oxidative phosphorylation; prompt on ETC or aerobic respiration or chemosmosis or terminal oxidation]
[10h] Many of the proteins in the electron transport chain belong to this class of redox proteins with a heme group. The P450 subfamily of these enzymatic proteins is frequently found attached to cell membranes.
ANSWER: cytochrome [accept specific answers like cytochrome c]
[10e] The electron transport chain takes place in the inner membrane of this organelle. This organelle was thought to have been absorbed by eukaryotes through endosymbiosis, and is known as the powerhouse of the cell.
ANSWER: mitochondria [or mitochondrion]
