Biology Quiz

What are carbohydrates broken down into?

Glucose

What are lipids broken down into?

Fatty acids + glycerol

What are proteins broken down into?

Amino acids

What are nucleic acids broken down into?

Nucleotides

What is the energy level of carbohydrates?

High

What is the energy level of lipids?

Very high

What is the energy level of proteins?

Moderate

What is the energy level of nucleic acids?

Low

Why do carbohydrates and lipids have high energy?

They have many C-C and C-H bonds

Glucose can build...

Complex carbs (starches + cellulose) and lipids

Plants need N, P, and S to make...

amino acids/proteins and nucleotides/nucleic acids.

Warmer temps =

Increased respiration

Too hot =

Enzymes/mitochondria stop working

Too cold =

Molecules move slowly or stop moving

Both alcoholic and lactic acid fermentation are:

• No Oxygen Needed: They are anaerobic, meaning they happen when there is no oxygen available (like during intense running or when yeast is sealed in a bottle).

• Make Little Energy: Both produce only a small amount of ATP (energy) for the cell.

Both alcoholic and lactic acid fermentation differ because:

• Use different enzyme.

• Have different final products.
