Hypothesis: As a group predict that aerobic exercise will consume more glucose because of oxidation phosphorylation which produces more ATP. Thus more reps will be done under this condition. Or in other words stage 1 of the lab will have more reps than stage 2 because there is more energy available. During aerobic respiration the continuous break down of sugar will allow more activity to be done versus anaerobic respiration which will just be able to use the energy it currently has, it will not be able to create more.

Could you tell when muscles went into anaerobic resp . what evidence?

There was a tight feeling in the muscles along with tension and cramping.
The oxygen could not be delivered to the cells quick enough to undergo oxidative phosphorylation and instead underwent anaerobic respiration in which oxygen is not needed. During anaerobic respiration, lactic acid fermentation occurred which causes the formation of lactase build up in the working muscles. This causes pain, stiffness, and fatigue which explains the symptoms experienced in the experiment. Panting was also experienced which occurs as a result of the body paying back the oxygen debt that was lost while lifting.

When your muscles run out of oxygen, your muscle cells quickly try to produce ATP using lactic acid fermentation. The buildup of lactic acid causes a painful, burning sensation.

Hot feeling after lifting. Explain using cellular respiration.

Exercising increases the body’s heat production through cellular respiration. The more active you are, the more energy you consume. As more energy is burned, more heat is created. When the muscles run out of oxygen, the cells attempt to produce ATP using lactic acid fermentation forming pyruvate then going back to step 6 of glycolysis. The hot feeling was experienced from lifting since this was an exergonic reaction which means energy was
