Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which molecule is the reactant of Glycolysis?
A
water
B
glucose
C
carbon dioxide
D
ATP
Explanation: 

Detailed explanation-1: -The reactant is glucose and the products are molecule of pyruvate, 2 ATPs and 2 NADH.

Detailed explanation-2: -Glycolysis is divided into two categories: aerobic (chemical reactions that occur with the presence of oxygen) and anaerobic (chemical reactions that do not require oxygen). An example of anaerobic glycolysis is fermentation. Glucose is the reactant; while ATP and NADH are the products of the Glycolysis reaction.

Detailed explanation-3: -Answer and Explanation: Glycolysis is the first stage of cellular respiration, and the reactants are one molecule of glucose and two molecules of ATP (adenosine triphosphate).

Detailed explanation-4: -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).

Detailed explanation-5: -Glycolysis starts with glucose and ends with two pyruvate molecules, a total of four ATP molecules and two molecules of NADH.
