Krebs Cycle and Electron Transport Chain Enzymes

Question

Krebs cycle and electron transport chain enzymes
A) are located within the mitochondria.
B) function anaerobically.
C) produce most of the lactic acid in the body.
D) account for the sandpaper-like appearance of the RER.

Accepted Answer

Both the Krebs cycle and electron transport chain enzymes are located within the mitochondria, an organelle responsible for producing energy in cells.

B, C, and D are incorrect because they either describe a different process (anaerobic respiration, lactic acid production) or have no connection to these enzymes (sandpaper-like appearance of the RER).
