How Creatine REALLY Works - The Biology Behind It

The video explains how bodybuilders use creatine for energy and muscle growth. It covers muscle contraction at the cellular level, focusing on sarcomeres, myosin, and actin. ATP is crucial for muscle contraction, acting as the body's energy currency. The video details ATP's role, its hydrolysis into ADP and inorganic phosphate, and the powerstroke mechanism. Creatine supplements help replenish ATP by converting ADP back to ATP, enhancing energy supply during exercise. The video also touches on creatine's effects on water retention and muscle growth hormones.

What are the main components involved in muscle contraction at the cellular level?

• Lipids, carbohydrates, and proteins

• DNA, RNA, and proteins

• Sarcomeres, myosin, and actin

• Nuclei, ribosomes, and mitochondria

What is the primary role of ATP in muscle contraction?

• To store genetic information

• To provide energy for the binding and flexing of myosin heads

• To transport oxygen in the blood

• To break down proteins into amino acids

How is ATP produced in the body?

• By absorbing sunlight

• By breaking down glucose during cellular respiration

• Through the process of osmosis

• Through photosynthesis

Why is creatine phosphate important for muscle cells?

• It stores oxygen for muscle cells

• It breaks down fats into fatty acids

• It converts ADP to ATP, replenishing energy for muscle contraction

• It helps in the digestion of food

What additional effects does creatine have on muscles besides ATP replenishment?

• It reduces muscle strength

• It causes muscle fatigue

• It increases water retention and affects hormones related to muscle growth

• It decreases muscle size
