Answer 1

Ans:

1. Option - D. 1.5-2.5

Explanation-

During oxidative phosphorylation oxygen molecules consumed may yields 1.5 to 2.5 molecules of ATP.

2. Option - D. High Protein supplement alone will lead to a greater mass or hypertrophy.

Explanation-

High Protein supplement not able to lead growth of mass alone. However dietary supplements of protein , carb and fibre is required.

3. Option - A. Poor bone growth

Explanation-

Relative energy deficiency in sport caused by low intake of food for maintaining low weight and prolonged excercise. In which growth of bone is normal but lack of nurishment weight loss, osteoporosis , stress fracture and risk of frequent infection, hair loss , fatigue present.

4. Option - D . Creatine is safe erogenic aids .

Explanation-

Blood doping, growth hormone, anabolic steroids, gamma hydroxybutaric acid these all illegal supplement are associated with a number of serious adverse effects, some are irreversible.

Creatine modestly improve athletic performance and appears to be relatively safe.
