MUSCLE ENERGETICS GLYCOLYSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Glucose enters cells and is committed to glycolysis with the addition of:
A
PFK Enzymes
B
-PO4 from ADP
C
-PO4 from ATP
D
Electrons from ATP
Explanation: 

Detailed explanation-1: -During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi–> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). The hydroxyl groups allow for phosphorylation. The specific form of glucose used in glycolysis is glucose 6-phosphate.

Detailed explanation-2: -The energy to split glucose is provided by two molecules of ATP.
