Anatomy Final Exam 2 (skel/mus)

Front

Bone Mass decreases as you get older. True or False?

Back

True

Front

Where is the energy stored and created in an ATP molecule?

Back

Chemical bond between the phosphate group and ATP molecule.

Front

What happens in the 3rd stage of fracture repair?

Back

Osteoblasts rebuild bone tissue.

Front

What produces ATP very quickly but lasts for a very short time (10-15 seconds)?

Back

ATP-PCR.

Front

What happens to the myofilaments when ATP allows for interactions between actin and myosin?

Back

Myosin will attach to actin to pull the sarcomere together.

Front

Define Osteoblasts.

Back

Cells that are responsible for bone formation.

Front

Define Osteoclasts.

Back

Cells that break down bone tissue.

Front

What is the role of ATP in muscle contraction?

Back

ATP provides the energy for myosin to pull actin, facilitating muscle contraction.

Front

What is the function of the sarcomere?

Back

The sarcomere is the basic unit of muscle contraction, composed of actin and myosin filaments.

Front

What is the Glycolysis/Lactic Acid System?

Back

A metabolic pathway that converts glucose into energy quickly, producing lactic acid as a byproduct.
