Unit 1 Biomolecule and Cell Review

Front

What is an enzyme?

Back

A protein that acts as a catalyst to speed up chemical reactions in biological processes.

Front

What happens to enzymes at high temperatures?

Back

Enzymes can become denatured, losing their structure and function.

Front

What is cellular respiration?

Back

A process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the simplified equation for cellular respiration?

Back

Glucose + Oxygen ⇒ Water + Carbon Dioxide + ATP Energy.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to the inside of a cell, causing the cell to lose water and shrink.

Front

What happens to a cell in a hypertonic solution?

Back

The cell shrinks in size due to water moving out of the cell.

Front

What is photosynthesis?

Back

The process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

Which organisms perform photosynthesis?

Back

Plants, algae, and some bacteria.

Front

What is homeostasis?

Back

The process by which living organisms maintain a stable internal environment despite external changes.

Front

How do cells maintain homeostasis?

Back

Cells regulate their internal conditions, such as water balance, temperature, and pH, through various mechanisms.
