Accepted Answer

Homeostasis

Question 4

Which of the following is NOT a major organ system of the human body?

Accepted Answer

Serosa system

Question 5

If a molecule has the formula $$C_{6}H$$_{12}$$O_{6}$, what type of macromolecule is it most likely to be?

Accepted Answer

Carbohydrate

Question 6

Which equation correctly represents the hydrolysis of a disaccharide?

Accepted Answer

$$C_{12}H$$_{22}$$O_{11} + H$$_{2}$$O \rightarrow 2C_{6}H$$_{12}$$O_{6}$

Question 7

Which of the following best describes a buffer's role in the human body?

Accepted Answer

Buffers help maintain a stable pH by neutralizing excess acids or bases.

Question 8

A solution has a pH of 5. Which of the following statements is correct?

Accepted Answer

The solution is acidic and has a higher concentration of $$H^{+}$$ ions than pure water.

Question 9

Which of the following is a correct statement about the difference between covalent and ionic bonds?

Accepted Answer

Covalent bonds involve the sharing of electrons, while ionic bonds involve the transfer of electrons.

Question 10

Which of the following best explains why water is considered a polar molecule?

Accepted Answer

Water has an uneven distribution of electrons, resulting in partial positive and negative charges.

Question 11

Which of the following is a function of ATP in the human body?

Accepted Answer

ATP provides energy for cellular processes such as muscle contraction.

Question 12

Which of the following best describes the difference between saturated and unsaturated fatty acids?

Accepted Answer

Saturated fatty acids have no double bonds between carbon atoms, while unsaturated fatty acids have one or more double bonds.

Question 13

Which of the following is a major function of phospholipids in the human body?

Accepted Answer

They form the structural basis of cell membranes.

Question 14

A patient has a genetic disorder affecting the primary structure of a protein. Which level of protein structure is directly altered?

Accepted Answer

The sequence of amino acids (primary structure)

Question 15

Which of the following best describes the role of enzymes in chemical reactions within the body?

Accepted Answer

Enzymes lower the activation energy required for reactions to occur.

Question 16

Which of the following is a correct description of a nucleotide found in DNA?

Accepted Answer

A nucleotide consists of a phosphate group, a deoxyribose sugar, and a nitrogenous base.

Question 17

Which of the following best explains why the structure of ATP is suited for its role as an energy carrier?

Accepted Answer

ATP contains high-energy phosphate bonds that can be easily broken to release energy.

Question 18

Which of the following best describes the difference between a monomer and a polymer?

Accepted Answer

A monomer is a single subunit, while a polymer is a chain of many subunits.

Question 19

Which of the following is a correct statement about the arrangement of electrons in shells?

Accepted Answer

Electrons are arranged in shells, with each shell holding a specific number of electrons.
