O

O
O
O
B. Mitochondrial
c. Anaerobic
D. Cellular

Answer 1

C. Anaerobic

Step-by-step explanation:

To produce energy for our muscles and organs, our body needs to breathe in oxygen. It is known as aerobic respiration, takes place in the mitochondria of our cells. But there are cases when our bodies cannot get enough oxygen, like when we're working out very hard or holding our breath.

Our cells then switch to anaerobic respiration. Like a backup plan for producing energy without oxygen. In our cells, anaerobic respiration takes place in the cytoplasm.

There's a catch, though! The amount of energy produced by anaerobic respiration is less than that of aerobic respiration. Also, it produces lactic acid, a waste product that can make our muscles feel fatigued and sore and, if it builds up, can cause painful cramps.

So, while anaerobic respiration is helpful in a pinch, it's not as efficient as aerobic respiration in the long run.
