Question

The end product of glycolysis
A) ATP (adenosine triphosphate)
B) Pyruvate
C) Protein
D) Carbohydrates

Answer 1

Hint: It is the important chemical compound that is used in biochemistry and it is the result of metabolism of glucose which is known as glycolysis. When oxygen is absent, then it creates lactate in ethanol in plants.

Complete Answer:
- Glycolysis is the series of 10 reactions that takes place in the cytoplasm. When glucose breaks down produces four products which includes ATP, 2 NADH and two pyruvates. But the end product of this glycolysis process is pyruvate.
- Pyruvate is an ester of the pyruvic acid. Glycolysis starts with one molecule of glucose and ends with the pyruvate molecules, 4 ATP molecules and 2 NADH molecules.
- The 2 ATP molecules used in the first half of the path help to prepare six carbon rings for cleavage.
- Pyruvate is an important product in the biochemical pathways. It is an organic molecule with a 3-carbon backbone.
- Pyruvate consists of two functional groups: ketone and carboxylate groups. Due to the presence of two functional groups pyruvate is keto acid.

$$C_6{H}_{12}{O}_6+2NA{D}^{+}+2ADP+2P\to 2C_3{H}_4{O}_3+2ATP+2NADH+2H^{+}$$

Thus, the correct answer is option B i.e., Pyruvate.

Note: Pyruvate involved in the anabolic synthesis of the amino acids and fatty acids. Pyruvate participates in the citric acid cycle. In the absence of oxygen, pyruvate can produce lactate by undergoing fermentation. The chemical formula of pyruvate is $C_3{H}_4{O}_3$. Pyruvate can be produced by 2 methods. First one, by metabolism of amino acids and secondly, glycolytic pathway.
