Where Does Glycolysis Occur in a Cell?

Answer – Glycolysis occurs in the cytoplasm of a cell.

Explanation:

Glycolysis is a central metabolic pathway that is used by all cells for the oxidation of glucose to generate energy in the form of ATP. In this process, one molecule of glucose is oxidized to generate two pyruvate molecules (products of glycolysis).

Glucose + 2 NAD+ + 2 ADP + 2 Pi → 2 Pyruvate + 2 NADH + 2 H⁺ + 2 ATP + 2 H₂O

The cytoplasm is a perfect site for glycolysis because the enzymes needed for this are located in the cytoplasm itself. Glucose is also available by diffusion within the cytoplasm. In addition, the energy released via glycolysis is used by cellular processes occurring within the cytoplasm.

Which are the inputs and outputs of Glycolysis?

Most CO₂ from catabolism is released during (A) Glycolysis, (B) The citric acid cycle, (C) Lactate fermentation, or (D) Electron transport.

Which of the following statements concerning glycolysis is incorrect? Group of answer choices: 1. It is an oxidation process in which no molecular oxygen is used; 2. All reactions take place in the cytosol of a cell; 3. There are two stages, each of which involves a series of five reactions; 4. No correct response.

The first reaction in Glycolysis is the phosphorylation of Glucose: Pi + Glucose → Glucose 6-Phosphate + water. This is a thermodynamically unfavorable process with a ∆G0’ = +13.8 kJ/mol. In a liver cell at 37°C, the concentrations of both phosphate and glucose are normally maintained at about 0.005 M each. What would be the equilibrium concentration of Glucose 6-Phosphate according to the above data? Note: In the biochemical standard state [H₂O] = 1.0 (this will help with the question below). When the reaction described in question number 3 is coupled to the hydrolysis of ATP, the equilibrium concentration of Glucose 6-Phosphate goes to: (A) 10.5, (B) 350, (C) 3000, (D) 77, (E) 4.5, (F) 55, (G) 550, (H) 652, or (I)1120.
