Question 5

A patient is experiencing muscle weakness due to a malfunction in the sodium-potassium pump. Which equation best describes the normal function of this pump?

Accepted Answer

$$3\mathrm{Na^+}$$ out, $$2\mathrm{K^+} in$$, using 1 ATP

Question 6

Which of the following best explains why water is considered a universal solvent?

Accepted Answer

Water is polar and can dissolve many ionic and polar substances.

Question 7

Which type of chemical bond is least likely to dissolve in water?

Accepted Answer

Covalent bond

Question 8

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

Accepted Answer

Mitochondrion

Question 9

A cell is placed in a hypertonic solution. What will most likely happen to the cell?

Accepted Answer

It will shrink as water leaves the cell.

Question 10

Which of the following is a correct statement about the Central Dogma of Biology?

Accepted Answer

DNA is transcribed into RNA, which is then translated into protein.

Question 11

Which of the following best describes the process of dehydration synthesis?

Accepted Answer

Joining monomers to form polymers by removing a water molecule

Question 12

Which of the following is a function of membrane proteins in the cell membrane?

Accepted Answer

Transporting substances across the membrane

Question 13

Which of the following statements about enzymes is correct?

Accepted Answer

Enzymes lower the activation energy and speed up chemical reactions.

Question 14

Which of the following is true about the structure of DNA?

Accepted Answer

DNA consists of two antiparallel strands held together by hydrogen bonds between complementary bases.

Question 15

During which phase of the cell cycle does DNA replication occur?

Accepted Answer

S phase

Question 16

Which of the following best describes the difference between passive and active transport across the cell membrane?

Accepted Answer

Passive transport moves substances down their concentration gradient without energy input, while active transport requires energy to move substances against the gradient.

Question 17

Which of the following is a correct example of a positive feedback loop in the human body?

Accepted Answer

Release of oxytocin during childbirth to intensify uterine contractions

Question 18

Which of the following best describes the role of ribosomes in the cell?

Accepted Answer

Synthesizing proteins by translating mRNA

Question 19

Which of the following statements about the fluid mosaic model of the cell membrane is correct?

Accepted Answer
