Front

What is active transport?

Back

Active transport is the process of moving molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy (ATP).

Front

What happens to body temperature if cooling mechanisms do not activate?

Back

If cooling mechanisms do not activate, the body would not cool down, potentially leading to overheating.

Front

What does a food web represent in an ecosystem?

Back

A food web represents all connections of energy flow throughout all organisms in a habitat, showing how they are interconnected.

Front

What is the purpose of cellular respiration?

Back

The purpose of cellular respiration is to turn glucose into energy in the form of ATP.

Front

What is the monomer for nucleic acids?

Back

The monomer for nucleic acids is a nucleotide.

Front

Define osmosis.

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is simple diffusion?

Back

Simple diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration without the use of energy.

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the need for energy, typically along the concentration gradient.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.

Front

What is the role of glucose in cellular respiration?

Back

Glucose serves as the primary energy source that is broken down during cellular respiration to produce ATP.
