What is Glucose?

Back

Glucose is a simple sugar and an important energy source in living organisms. It is a carbohydrate that is produced during photosynthesis and is used by cells for energy.

What happens to a red blood cell in a hypertonic solution?

Back

In a hypertonic solution, a red blood cell will shrink because it loses water molecules to the surrounding solution.

Front

What are proteins made of?

Back

Proteins are made of amino acids, which are linked together by peptide bonds.

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is a unicellular organism?

Back

A unicellular organism is an organism that consists of a single cell, such as bacteria and protists.

Front

What is the role of ATP in cells?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to another solution, leading to the movement of water out of cells.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration, while osmosis specifically refers to the movement of water.

Front

What are the main components of a cell?

Back

The main components of a cell include the cell membrane, cytoplasm, nucleus, and organelles.
