Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.
Glycolysis takes place in the (g)cytoplasm. Two molecules of ATP and two molecules of (h)NADH are formed for every glucose molecules that is broken down. (i) Aerobic respiration takes place in the (j) mitochondria. It is aerobic because the process requires (k)oxygen.
the circulatory distributes these nutrients. this maintains a cycle of balance or homeostasis and keeps glucose levels relatively steady unless you have diabetes
