Question

Which of the following statements about enzymes is true?

Question 1 options:

Enzymes increase the activation energy required for a reaction

Enzymes are consumed in the reactions they catalyze

Enzymes are highly specific and can catalyze multiple reactions

Enzymes lower the activation energy of a reaction

Question 2 (1 point)
Which of the following statements correctly describes the differences between passive and active transport mechanisms?

Question 2 options:

Passive transport requires protein channels, while active transport does not

Active transport moves substances against their concentration gradient, while passive transport moves substances down their concentration gradient

Passive transport can occur only in the presence of a semipermeable membrane, whereas active transport can occur in any environment

Active transport relies on diffusion, while passive transport uses energy from ATP
