Question

What organelle does cellular respiration, TCA cycle, and electron transport take place?

Answer 1

Cellular respiration:

1. Cellular respiration is the process in which organisms use oxygen to break the food molecules to get chemical energy for the functions of cells.
2. Cellular respiration takes place in the organelle, mitochondria.

TCA cycle:

1. TCA cycle is used by all aerobic organisms to release stored energy via oxidation of acetyl CoA derived from fats, carbohydrates, and proteins into ATP.
2. The cell organelle in which the TCA cycle occurs in mitochondria.

Electron transport chain:

1. The electron transport chain consists of a series of enzymatic reactions within the inner membrane of the mitochondria.
2. These are cell organelles that release and store energy for all physiological needs.
