Question

Pyruvate is formed from glucose in the_______ of a cell?

• A. mitochondria
• B. cytoplasm
• C. nucleus
• D. ribosome

Answer 1

Answer:

B. cytoplasm

• Pyruvate is formed from glucose through glycolysis, a metabolic process that takes place in the cytoplasm of a cell.

• Pyruvate is indeed the end product of glycolysis, a fundamental metabolic pathway.

• Glycolysis is the sequence of reactions that breaks down one molecule of glucose (a six-carbon sugar) into two molecules of pyruvate (a three-carbon molecule).

• This process occurs in the cytoplasm of both prokaryotic and eukaryotic cells.

• Glycolysis is an anaerobic process, meaning it does not directly require oxygen.

• It also produces a small net gain of ATP (adenosine triphosphate), the cell's primary energy currency, and NADH (nicotinamide adenine dinucleotide), a reduced coenzyme that carries high-energy electrons.
