During exercise, muscle cells immediately use ATP as the energy source for contractions.

The only immediate source of energy for muscular contraction is ATP. Within muscle fibers, ATP is replenished by creatine phosphate (anaerobic respiration), glycolysis (anaerobic respiration), and cellular respiration (aerobic respiration). As the duration and intensity increase, carbohydrates (glucose/glycogen) become the primary source of fuel. If exercise is sustained for an extended period of time, fatty acids will be used as a fuel source when glycogen stores are nearly depleted.

ATP is a form of instant energy. The body cannot obtain energy directly from glucose. Glucose is not a direct source of energy. Instead, the body uses the energy released from the breakdown of glucose to drive ADP phosphorylation.

ratelena [41]

Answer:

A. Aquaculture will increase more rapidly due to the new fish’s rapid growth and economic value.

Explanation:

The introduction of genetically modified fish would further promote the raising of fish in captivity.

This would also reduce the reliance on capture fisheries production.

More tones of fish would be produced yearly as a result of the rapid growth of the genetically modified fish, and therefore, this would lead to the rapid growth of Aquaculture.
