Biology Quiz on Enzymes and Photosynthesis

Which type of inhibition involves the inhibitor directly binding at the active site of the enzyme?

• Direct inhibition

• Indirect inhibition

• Competitive inhibition

• Non-competitive inhibition

What does it mean for a membrane to be selectively permeable?

• ATP is necessary for molecules to be transported across the cell mam

• A high to low concentration is required for molecules to pass through the membrane

• Water molecules can flow freely from outside to inside the cell

• Allows for certain molecules to pass through the membrane but can block others

During photosynthesis, what is the specific structure called that allows oxygen and carbon dioxide into the chloroplast?

• Thylakoid

• Chloroplast

• Stomata

• Granum

True or false: chloroplasts are the structure in plants that capture light to generate light reactions

• TRUE

• FALSE

What will happen to a cell placed in a hypertonic solution?

• It will shrivel

• It will burst

• It will stay the same

• It will multiply

True or False: the entire process of cellular respiration occurs in the mitochondria.

• True

• False

The first law of thermodynamics states that:

• Entropy of a system always increases

• When temperature of a system approaches zero, entropy reaches equilibrium

• Endergonic reactions require energy while exergonic reactions release energy

• Energy can be transferred/transformed but cannot be created or destroyed
