Question

During strenuous exercise glucose is converted into
(a) Glycogen
(b) Pyruvic acid
(c) Starch
(d) Lactic acid

Answer 1

This is produced by bacteria in the yogurt and also in our guts. It is a chemical byproduct of anaerobic respiration. In solid-state it is white in color and is easily miscible in water.

Complete answer:
Glucose is converted into lactic acid during strenuous exercise. for all the cells present in our body the main or the most important source of energy is glucose. It undergoes metabolism to form ATP in the presence of oxygen. When we do strenuous exercise our body needs lots of energy. This means energy in the form of ATP is essential for the contraction of muscles and is required in sufficient amounts during strenuous exercise. But this demand is not fulfilled during strainers exercise due to rapid breathing action and glucose has to undergo metabolism in the absence of oxygen resulting in the formation and accumulation of lactic acid.
-From glucose lactic acid is produced during the process of anaerobic respiration where the cells produce energy in the absence of oxygen.
-The presence of lactic acid in a high amount in our muscles can cause discomfort and disturbances in different metabolic pathways of our body.
-Glycogen: When we have a large quantity of glucose present in our body then it starts converting into glycogen. It is stored in the liver and muscles for further use whenever required.
-Pyruvic acid: This is the main or key acid present in all the living cells as it is an important constituent in many metabolic pathways such as glycolysis and Kreb’s cycle.
-Starch: This is prepared and stored in the green plants. In the presence of certain enzymes starch breaks into simple constituents which provides the nutrients for cell growth.

So, the correct answer is,’ Lactic acid’.

Note:
-Lactic acid is produced in our body when there is low oxygen present.
-If more lactic acid gets accumulated in our body it may result in muscle pain, muscular fatigue, and cramps.
-In our body lactic acid build-up generally occurs during strenuous exercise.
