Biology Midterm Review

Front

What is Cellular Respiration?

Back

Cellular Respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

Why is oxygen important in Cellular Respiration?

Back

Oxygen is a reactant in aerobic cellular respiration, allowing for the efficient production of ATP.

Front

What happens to proteins in an acidic pH environment?

Back

Proteins essential to the function of the cell might denature, losing their structure and function.

Front

Why is the 3D shape of an enzyme important?

Back

The 3D shape of an enzyme determines which specific reaction it can catalyze.

Front

Where does ATP energy conversion occur in the cell?

Back

ATP energy conversion occurs in the mitochondria.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that allows substances to cross membranes with the assistance of special proteins.

Front

What is the role of the mitochondria in cellular respiration?

Back

Mitochondria are the organelles where sugars are converted into ATP energy.

Front

What is denaturation in proteins?

Back

Denaturation is the process where proteins lose their natural structure due to external stress, such as extreme pH.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

Front

What is the function of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process.
