ATP production through aerobic respiration

Question 3

Which of the following best describes the main function of epithelial tissue?

Accepted Answer

Covering and lining surfaces for protection, absorption, and secretion

Question 4

A biopsy of a patient's lung reveals a single layer of flat cells lining the alveoli. Which type of epithelium is this?

Accepted Answer

Simple squamous epithelium

Question 5

Which of the following is a function of the basal lamina in epithelial tissue?

Accepted Answer

Acts as a selective filter and provides structural support

Question 6

A gland that releases its product by exocytosis without losing any part of the cell is classified as:

Accepted Answer

Merocrine

Question 7

Which connective tissue fiber type provides the greatest tensile strength?

Accepted Answer

Collagen fibers

Question 8

A patient presents with swelling (edema) in their ankle after an injury. Which type of connective tissue is primarily responsible for soaking up the excess fluid?

Accepted Answer

Areolar connective tissue

Question 9

Which of the following best describes the difference between 'blast' and 'cyte' cells in connective tissue?

Accepted Answer

'Blast' cells are immature, actively dividing cells that secrete matrix; 'cyte' cells are mature, less active cells that maintain the matrix.

Question 10

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

Accepted Answer

Initiating muscle contraction

Accepted Answer

Dense regular connective tissue

Question 12

Which of the following best explains why epithelial tissues have a high regenerative capacity?

Accepted Answer

They are exposed to frequent friction and damage, requiring rapid cell replacement.

Accepted Answer

Muscle tissue: movement

Question 14

A sample of tissue is found to have cells embedded in a hard matrix containing calcium salts. Which tissue is this?

Accepted Answer

Bone (osseous tissue)

Question 15

Which of the following best describes the function of microvilli on epithelial cells?

Accepted Answer

Increase surface area for absorption

Question 16

A gland that releases its product by the rupture of entire cells is classified as:

Accepted Answer

Holocrine

Question 17

Which of the following equations correctly represents the relationship between the number of protons ($$p$$), neutrons ($$n$$), and electrons ($$e) in a $$neutral atom?

Accepted Answer

$$p = e$$

Question 18
