Glycolysis requires
A
ATP
B
Oxygen
C
sunlight
D
NADP+
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: -Glycolysis requires specific ingredients to work. The inputs of glycolysis include a living cell, cytoplasmic enzymes, glucose, and energy transfer molecules nicotinamide adenine dinucleotide (NAD+) and adenosine triphosphate (ATP).ADP. Hence ATP, ADP, NAD+, Glucose, cytoplasmic enzymes are required in glycolysis.

Detailed explanation-3: -The first and third steps of glycolysis are both energetically unfavorable. This means they will require an input of energy in order to continue forward. Per glucose molecule, 1 ATP is required for each of these steps. Therefore, a total of 2 ATP is needed during the energy investment phase of glycolysis.

Detailed explanation-4: -First ATP is produced when glyceraldehyde-3-phosphate ⇢ 1, 3 diphosphoglycerate. Secondly ATP is produced when phosphoenolpyruvate ⇢ pyruvate. These reactions occur twice for both molecules of 3-phosphate. Thus, a total of 4 ATPs are produced during glycolysis.
