Q: Which equation correctly represents the process of ATP regeneration during aerobic metabolism in skeletal muscle?

$$\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \rightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} + 36\text{ATP}$$

Question 1

Which of the following best describes the functional difference between compact bone and spongy bone?

Accepted Answer

Compact bone forms the outer layer of bones and provides strength for weight-bearing, while spongy bone contains trabeculae that support bone marrow and reduce bone weight.

Question 2

Which equation correctly represents the process of ATP regeneration during aerobic metabolism in skeletal muscle?

Accepted Answer

$$	ext{C}_6	ext{H}_{12}	ext{O}_6 + 6	ext{O}_2 ightarrow 6	ext{CO}_2 + 6	ext{H}_2	ext{O} + 36	ext{ATP}$$

Question 3

A patient with osteoporosis is most likely to have which of the following changes in bone remodeling?

Accepted Answer

Decreased osteoblast activity and increased osteoclast activity.

Question 4

Which structure is responsible for the attachment of muscle to bone?

Accepted Answer

Tendon

Question 5

Which of the following is a function of the sarcoplasmic reticulum in skeletal muscle cells?

Accepted Answer

Storing and releasing calcium ions during muscle contraction

Question 6

Which of the following bones is part of the axial skeleton?

Accepted Answer

Sternum

Question 7

Which of the following best explains the role of red bone marrow?

Accepted Answer

It produces red blood cells, white blood cells, and platelets.

Question 8

Which of the following is a correct statement about the epiphyseal plate?

Accepted Answer

It is a layer of hyaline cartilage where bone growth in length occurs during childhood and adolescence.

Question 9

Which of the following correctly describes the sliding filament theory of muscle contraction?

Accepted Answer

Myosin heads bind to actin, pulling the actin filaments toward the center of the sarcomere, resulting in muscle contraction.

Question 10

Which of the following is a major function of the cranium?

Accepted Answer

Protecting the brain

Question 11

Which of the following is a common function of spinal curvatures and intervertebral discs?

Accepted Answer

They increase the flexibility and shock absorption of the vertebral column.

Question 12

Which of the following is true regarding the concentration of blood calcium and its regulation?

Accepted Answer

Parathyroid hormone increases blood calcium by stimulating osteoclast activity.

Question 13

Which of the following is a structural characteristic of synovial joints?

Accepted Answer

Presence of a joint cavity filled with synovial fluid

Question 14

Which of the following best describes the role of ATP in muscle contraction?

Accepted Answer

ATP is required for myosin heads to detach from actin and reset for another contraction cycle.

Question 15

Which of the following is a correct statement about the structure of a sarcomere?

Accepted Answer

The sarcomere is the region between two Z discs and contains overlapping actin and myosin filaments.

Question 16

Which of the following is a major function of the pelvic girdle?

Accepted Answer

Supporting the weight of the upper body and transferring it to the lower limbs

Question 17

Which of the following is a correct statement about bone markings?

Accepted Answer

Bone markings serve as sites for muscle, ligament, and tendon attachment, as well as passages for nerves and blood vessels.

Question 18

Which of the following is a correct statement about the function of intervertebral discs?

Accepted Answer

They act as shock absorbers and provide flexibility to the spine.

Question 19

Which of the following is a correct statement about the process of bone remodeling?

Accepted Answer

Bone remodeling is a continuous process involving both osteoblasts and osteoclasts to maintain bone strength and mineral homeostasis.

Question 20

Which of the following is a correct statement about the role of myoglobin in muscle tissue?

Accepted Answer

Myoglobin stores oxygen for use during muscle activity.
