Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When glycolysis occurs,
A
a molecule of glucose is split
B
two pyruvate are made
C
some ATP is produced
D
all of these
Explanation: 

Detailed explanation-1: -Glycolysis occurs both during aerobic and anaerobic respiration . It is the first pathway for the oxidative breakdown of glucose.

Detailed explanation-2: -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-3: -Glycolysis takes place in the cell’s cytoplasm. Glycolysis is a process that happens in all living organisms, both aerobic and anaerobic.

Detailed explanation-4: -Glycolysis is the process in which glucose is broken down to produce energy. It produces two molecules of pyruvate, ATP, NADH and water. The process takes place in the cytoplasm of a cell and does not require oxygen. It occurs in both aerobic and anaerobic organisms.

Detailed explanation-5: -Phosphorylation. A hexose sugar (typically glucose) is phosphorylated by two molecules of ATP (to form a hexose bisphosphate) Lysis. Oxidation. ATP formation.
