Under what conditions will the body use significant amounts of protein for energy during exercise?a.Inadequate calorie intakeb.I
irga5000 [103]

Answer:

Hello!

The answer is b. inadequate calorie intake and inadequate carbohydrate storage

Explanation:

Our body requires energy to carry out daily activities and body functions. This energy is available to the body in three forms:

  1. carbohydrates
  2. fats
  3. proteins

Carbohydrates are the first and most readily available source of energy as starch and complex carbohydrates and sugars are immediately broken down into glucose which is available for body cells. Excess glucose is also stored as glycogen in the muscles. During exercise, carbohydrates, particularly, glucose are the first sources of energy for the body.

Fats provide the highest energy of all three (9 kilocalories compared to 4 of protein and carbohydrates). Fats are stored in the body in the form of adipose tissues or body fat. Any excess energy is readily stored by the body in the form of fats.

As proteins are not stored by the body, they are the last to be broken down during strenuous or prolonged exercise. Protein, particularly the skeletal muscle is the last to be used for energy in case of low calorie intake and inadequate carbohydrate stores.

can someone explains (summarize) what photoperiodism is? And if it’s the same as photoperiodism
kompoz [17]

Answer: photoperiodism means the response of an organism to seasonal changes in day length. Photoperiodism isn't the same as Photoperiod because Photoperiodism merely refers to the potential of the plant to incite flowering relative to the changes in the photoperiod. Thus, photoperiod is a light duration or the length of day and night, while photoperiodism is the effect of light duration on the plant’s growth.
