Question

Is hexokinase found in the cytosol?

Answer 1

Hexokinase

1. The first enzyme in glycolysis, hexokinase, is responsible for phosphorylating glucose by ATP into glucose-6-P.
2. As healthy red cells get older, their activity rapidly drops.

Cytosol

1. A cell's internal liquid medium is called the cytosol.
2. A part of the cytoplasm is the cytosol.
3. The cytosol, all organelles, and the liquid interiors of the organelles are all included in the cytoplasm.
4. It catalyses the conversion of glucose to glucose-6-phosphate, the first step in glycolysis.
5. Glycolysis (the process of converting glucose to pyruvate) results in a net gain of ATP and the reduction of the coenzyme NAD to NADH.
6. It is one of the rate-limiting enzymes in glycolysis.
7. Animal cytosol is home to several important metabolic processes, including protein production, the pentose phosphate route, glycolysis, and gluconeogenesis.
8. Yes, the cytosol contains hexokinase.
