What is the starting molecule for glycolysis?
A
Glucose
B
ADP
C
Oxygen
D
Pyruvic Acid
Explanation: 

Detailed explanation-1: -Glycolysis is a series of reactions that occurs when glucose molecules split into two 3-carbon molecules known as pyruvates, which then release energy in the form of ATP. Starting material for glycolysis is glucose.

Detailed explanation-2: -The first step in glycolysis is catalyzed by hexokinase, an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. Hexokinase phosphorylates glucose using ATP as the source of the phosphate, producing glucose-6-phosphate, a more reactive form of glucose.

Detailed explanation-3: -Glucose is first converted to fructose-1, 6-bisphosphate in a series of steps that use up two ATP. Then, unstable fructose-1, 6-bisphosphate splits in two, forming two three-carbon molecules called DHAP and glyceraldehyde-3-phosphae.
