When working muscle cells are deprived of oxygen they produce?

Answers

Answer 1
Answer: lactic acid

During intense exertion or activity involving the muscles, there arises a need for a sudden short term burst of energy. This need for energy is so demanding that it cannot be satisfied through the normal mechanism  whereby energy is supplied through aerobic respiration using oxygen.Therefore the muscle cells must rely on other mechanisms that do not rely on oxygen to fuel muscle contraction and this is where they resort to anaerobic respiration which uses pyruvate to play the role of oxygen as the final electron acceptor. In the process, pyruvate accepts an electron and is reduced to lactic acid in the muscle tissues.

Which one of the following statements about carbohydrates is TRUE?a. Carbohydrates are a friendly fuel.
b. Carbohydrates are fattening.
c. A teaspoon of carbohydrate contains twice as many calories as the same amount of fat.
d. Carbohydrates are stored, rather than burned, by the body.

Answers

Carbohydrates are a friendly fuel is true. Therefore, option (A) is correct.

Carbohydrates are an essential macronutrient and serve as the primary source of energy for the body. When consumed, carbohydrates are broken down into glucose, which is used by cells to produce ATP (adenosine triphosphate), the energy currency of the body. Carbohydrates provide quick and easily accessible energy for bodily functions, physical activity, and brain function.

Carbohydrates themselves are not inherently fattening. Weight gain occurs when there is an excess of calories consumed from any macronutrient, including carbohydrates, that exceeds the body's energy needs.
