Fall Midterm Review (OnRamps Biology)

Front

What is the reason large bodies of water do not quickly fluctuate in temperature?

Back

Water has a high heat capacity, allowing it to absorb and retain heat without significant temperature changes.

Front

What regulates most cellular activities?

Back

Enzymes are proteins that act as catalysts to regulate cellular processes.

Front

What type of protein forms an ion channel through a membrane?

Back

A transmembrane protein spans the membrane and facilitates the transport of ions.

Front

What happens to ATP to release free energy?

Back

Free energy is released from ATP when a phosphate group is removed.

Front

What is hydrogen bonding?

Back

Hydrogen bonding is the attraction between the hydrogen atom of one molecule and the oxygen atom of another molecule.

Front

Define high heat capacity.

Back

High heat capacity is the ability of a substance to absorb and store large amounts of heat energy without a significant change in temperature.

Front

What role do enzymes play in biological processes?

Back

Enzymes act as catalysts that speed up chemical reactions in cells.

Front

What is a transmembrane protein?

Back

A transmembrane protein is a type of protein that spans the entire membrane and is involved in transporting substances across it.

Front

Explain the process of ATP hydrolysis.

Back

ATP hydrolysis is the reaction where ATP is broken down into ADP and a phosphate group, releasing energy for cellular work.

Front

What is the significance of hydrogen bonds in water?

Back

Hydrogen bonds give water its unique properties, such as high surface tension and the ability to dissolve many substances.
