Which of the following best describes the role of carbohydrates in animal cells?

They provide energy for cellular activities

Which of the following best explains why lipids are important for cells?

They form barriers that protect and organize cells

They provide instructions for making proteins

They speed up chemical reactions

Why do living organisms need nucleic acids?

To store and transmit genetic information

Which statement best describes the relationship between enzymes and substrates?

Enzymes speed up the breakdown or synthesis of substrates

Enzymes are broken down by substrates

Enzymes store substrates for later use

Which of the following best explains why carbohydrates are considered a primary energy source for cells?

They are easily broken down into glucose, which cells use for energy

They are used to build cell membranes

Which of the following best describes how proteins are involved in the structure and function of cells?

They act as enzymes and provide structural support

They store energy for long-term use

They are the main component of cell walls

Explain why removing all lipids from a cell membrane would affect the cell’s ability to function.

The cell would lose its barrier and could not control what enters or leaves

The cell would have more energy

The cell would produce more proteins

The cell would store more genetic information

A scientist wants to test the effect of temperature on enzyme activity. Which variable should the scientist measure to determine the rate of the enzyme-catalyzed reaction?

Amount of substrate used up over time

A student observes that when Biuret reagent is added to a food sample, the solution turns purple. Which biomolecule is present, and what does this indicate about the food?

Protein; the food contains amino acids

Carbohydrate; the food is a good energy source

Nucleic acid; the food stores genetic information

Given the following scenario: A person eats a meal high in carbohydrates. Predict what will happen to the glucose levels in their blood and explain why.

Glucose levels will increase because carbohydrates are broken down into glucose

Glucose levels will decrease because carbohydrates are not digested

Glucose levels will stay the same because carbohydrates are not absorbed

Glucose levels will decrease because glucose is stored as fat

A diagram shows a cell with a damaged cell membrane. What is the most likely effect on the cell’s ability to maintain homeostasis?

The cell will lose control over what enters and leaves, disrupting homeostasis

The cell will be better at storing energy

The cell will produce more proteins

The cell will divide more rapidly

A student is investigating the effect of enzyme concentration on the rate of a reaction. Which result would support the hypothesis that more enzyme increases reaction rate?

The reaction rate increases as enzyme concentration increases

The reaction rate decreases as enzyme concentration increases

The reaction rate stays the same regardless of enzyme concentration

Explain how the structure of a protein determines its function in the body.

The sequence of amino acids determines the protein’s shape, which determines its specific function

The protein’s function is unrelated to its structure

All proteins have the same structure and function

Proteins only function as energy storage

A student claims that nucleic acids are not important for cell function because they do not provide energy. Use your knowledge of biomolecules to evaluate this claim.

The claim is incorrect because nucleic acids are essential for storing and transmitting genetic information

The claim is correct because only carbohydrates provide energy

The claim is correct because nucleic acids are not found in cells

The claim is incorrect because nucleic acids are the main component of cell membranes
