Detailed explanation-1: -Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae ).

Detailed explanation-2: -The correct option is A True Glycolysis takes place in the cytoplasm.

Detailed explanation-3: -To summarize, glycolysis occurs in the cytoplasm to break up glucose by cleaving it into two phosphorylated 3-carbon compounds and then oxidizing these compounds to form pyruvate and net two molecules of ATP.

Detailed explanation-4: -Answer and Explanation: The process which takes place in the cytoplasm of a cell is glycolysis. It is the first step of cellular respiration and occurs in the presence or absence of oxygen to oxidize glucose to produce two molecules of pyruvate, two NADH and two ATP molecules.

Detailed explanation-5: -Glycolysis is a cytoplasmic pathway which breaks down glucose into two three-carbon compounds and generates energy. Glucose is trapped by phosphorylation, with the help of the enzyme hexokinase. Adenosine triphosphate (ATP) is used in this reaction and the product, glucose-6-P, inhibits hexokinase.
