GLYCOLYSIS

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 cytoplasm of both prokaryotic and eukaryotic cells.

Detailed explanation-4: -In organisms that perform cellular respiration, glycolysis is the first stage of this process. However, glycolysis doesn’t require oxygen, and many anaerobic organisms-organisms that do not use oxygen-also have this pathway.

Detailed explanation-5: -Glycolysis takes place in the cell’s cytoplasm. Glycolysis is a process that happens in all living organisms, both aerobic and anaerobic.
