Answer;
-Electron transport chain.
Explanation;
-Aerobic cellular respiration is divided into three phases, namely; glycolysis, citric acid cycle and the electron transport chain. Aerobic respiration produces 38 ATP molecules (2 ATP from glycolysis, 2 ATP from the Krebs cycle, and about 34 ATP from the electron transport system). Oxidative phosphorylation at the electron transport chain by a process called chemiosmosis process accounts for the most ATP.
Involuntary because we have no control over opening and closing our pupils, it does it by itself as a response to the outside environment.
Homeostasis is the ability of an organism to change internally or externally in relation to its environment
1.) Mitosis is the splitting of a parent cell into two daughter cells. When mitosis occurs the DNA is copied, making double the amount of chromosomes in the parents cell which will late be divided into two separate cells when the cell pinches in the middle.
