Q: Which equation best represents the relationship between catabolism and anabolism in metabolism?

Catabolism: $$\text{Large molecules} \rightarrow \text{Small molecules} + \text{Energy}$$; Anabolism: $$\text{Small molecules} + \text{Energy} \rightarrow \text{Large molecules}$$

Q: Which equation represents the movement of molecules during simple diffusion?

$$\text{Net movement} = \text{High concentration} \rightarrow \text{Low concentration}$$

Q: Which equation best represents the process of endochondral ossification?

$$\text{Cartilage} \rightarrow \text{Bone}$$

Question 1

Which of the following best describes the difference between negative and positive feedback mechanisms in homeostasis?

Accepted Answer

Negative feedback reverses a change to maintain stability, while positive feedback amplifies a change until a specific outcome is reached.

Question 2

A patient presents with yellowing of the skin and eyes. Which term best describes this condition, and what is its most likely cause?

Accepted Answer

Jaundice; accumulation of bilirubin due to liver dysfunction

Question 3

Which equation best represents the relationship between catabolism and anabolism in metabolism?

Accepted Answer

Catabolism: $$	ext{Large molecules} ightarrow 	ext{Small molecules} + 	ext{Energy}$$; Anabolism: $$	ext{Small molecules} + 	ext{Energy} ightarrow 	ext{Large molecules}$$

Question 4

Which organelle is primarily responsible for ATP production in eukaryotic cells?

Accepted Answer

Mitochondrion

Question 5

A cell is placed in a solution with a higher solute concentration than its cytoplasm. Which process will occur, and what is the expected outcome?

Accepted Answer

Osmosis; water will move out of the cell, causing it to shrink

Question 6

Which tissue type is most likely to regenerate after injury, and why?

Accepted Answer

Epithelial tissue, because it has a high rate of cell division

Question 7

Which of the following best describes the function of the periosteum?

Accepted Answer

It surrounds the outer surface of bone, provides nourishment, and serves as an attachment point for tendons and ligaments.

Question 8

Which equation represents the movement of molecules during simple diffusion?

Accepted Answer

$$	ext{Net movement} = 	ext{High concentration} ightarrow 	ext{Low concentration}$$

Question 9

Which bone cell is responsible for breaking down bone matrix, and what is the process called?

Accepted Answer

Osteoclast; resorption

Question 10

A burn that affects both the epidermis and the entire dermis is classified as:

Accepted Answer

Third-degree burn

Question 11

Which of the following is a function of melanin in the skin?

Accepted Answer

Protects against UV radiation by absorbing light

Question 12

Which equation best represents the process of endochondral ossification?

Accepted Answer

$$	ext{Cartilage} ightarrow 	ext{Bone}$$

Question 13

Which of the following best describes the effect of parathyroid hormone (PTH) on bone tissue?

Accepted Answer

PTH stimulates osteoclasts to break down bone matrix, increasing blood calcium levels.

Question 14

Which of the following is NOT a function of bone tissue?

Accepted Answer

Production of hormones

Question 15

Which membrane lines body cavities that do NOT open to the exterior and is composed of simple squamous epithelium and areolar connective tissue?

Accepted Answer

Serous membrane

Question 16

Which of the following best describes the main difference between mitosis and meiosis?

Accepted Answer

Mitosis produces two identical cells; meiosis produces four genetically unique cells.

Question 17

Which equation best represents the process of osmosis?

Accepted Answer

$$	ext{Water moves from low solute concentration to high solute concentration across a semipermeable membrane}$$

Question 18

Which of the following is a sign rather than a symptom?

Accepted Answer

Fever measured by thermometer

Question 19

Which layer of the epidermis is responsible for the generation of new skin cells?

Accepted Answer

Stratum germinativum (basale)

Question 20

Which of the following best describes the composition of bone ground substance?

Accepted Answer

Calcium phosphate, calcium carbonate, and proteoglycans
