Understanding Creatine and Muscle Contraction

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

• Nuclei, cytoplasm, and cell membrane

• Mitochondria, ribosomes, and lysosomes

• Golgi apparatus, endoplasmic reticulum, and vacuoles

• Sarcomeres, myosin, and actin

What is the primary function of ATP in muscle contraction?

• To store genetic information

• To transport oxygen in the blood

• To break down proteins

• To provide energy for muscle contraction

How is ATP produced in the body?

• Through photosynthesis

• Through osmosis

• Via fermentation

• By cellular respiration

What role does creatine phosphate play in muscle cells?

• It converts ADP to ATP, replenishing energy

• It stores oxygen for muscle use

• It breaks down glucose for energy

• It transports nutrients to muscle cells

Besides ATP replenishment, what is another effect of creatine on muscles?

• It increases water retention and affects muscle growth hormones

• It reduces water retention

• It lowers muscle temperature

• It decreases muscle size
