Transition step:

Each pyruvic acid molecule is transported to the

A one carbon molecule called is released from each molecule of pyruvic acid and the remaining 2-carbon unit that is formed is called .

CoenzymeA is then attached to _ to form .

Additional energy is stored as reduced molecules

mitochondrion, carboxylic group , acetyl group, acetyl group, acetyl CoA, NADH

Explanation:

Two pyruvate molecules remain at the end of glycolysis which still have a lot of extractable energy. The next step in storing the remaining energy in the form of ATP is oxidation by pyruvate. The transition steps are as following:

Hence the correct order to fill the blanks is  mitochondrion, carboxylic group , acetyl group, acetyl group, acetyl CoA, NADH.

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.

idk im sorry.
