Which of the following enzymes are involved in coupled reactions in glycolysis? (select all that apply.) phosphoglycerate kinase fructose-bisphosphate aldolase enolase hexokinase

Hexokinase, Phosphofructokinase, Phosphoglycerate kinase and Pyruvate kinase

Explanation:

Coupled reactions are reactions that require energy by one process and is supplied by another; where the energy is transferred from one side of the reaction to the other.

In glycolysis, four (4) reactions undergo coupled reactions

1. Reaction one: which is the phosphorylation of glucose to glucose-6-phosphate coupled to the hydrolysis of ATP to ADP and Pi catalyzed by hexokinase.

2. Reaction three: The phosphorylation of fructose-6-phosphate to fructose-1-6-bisphosphate and the hydrolysis of ATP, catalyzed by phosphofructokinase

3. Reaction seven: Phosphoglycerate kinase catalyzes the conversion of Bisphoglycerate to 3-phoshoglycerate and the production of ATP from ADP

4. Reaction ten: Pyruvate kinase catalyzes the conversion of enol phosphate to the enolic form of pyruvate with the synthesis of ATP.

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.
