Biology Final Exam

Front

What is the monomer of carbohydrates?

Back

Monosaccharides are the monomers (building blocks) of carbohydrates.

Front

What is active transport?

Back

Active transport is the process of moving substances across a cell membrane against their concentration gradient, which requires energy.

Front

How many cells are produced at the end of mitosis?

Back

Mitosis results in the production of 2 diploid cells.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of molecules diffusing through a protein channel along the concentration gradient.

Front

If a cell has 24 chromosomes, how many chromosomes will each daughter cell have after mitosis?

Back

Each daughter cell will have 24 chromosomes.

Front

What are the four main types of biomolecules?

Back

The four main types of biomolecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

What is the primary function of carbohydrates in living organisms?

Back

Carbohydrates serve as a primary source of energy and are involved in structural functions.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy and moves substances down their concentration gradient, while active transport requires energy to move substances against their concentration gradient.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules across a selectively permeable membrane.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions in the body by lowering the activation energy.
