Fall: Honors Benchmark #2

Front

What is the role of phosphate in ATP?

Back

Phosphate is an important component of ATP that is needed to transfer and release energy directly.

Front

What is the active site of an enzyme?

Back

The active site is the region on an enzyme where substrate molecules bind and undergo a chemical reaction.

Front

What are the two types of passive transport?

Back

The two types of passive transport are osmosis and diffusion.

Front

What is the primary source of quick energy for the body?

Back

Carbohydrates are the primary source of quick energy that the body uses for simple tasks.

Front

What phase of mitosis is characterized by the separation of sister chromatids?

Back

Anaphase is the phase of mitosis where sister chromatids are separated and pulled to opposite poles of the cell.

Front

Define osmosis.

Back

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

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What is the significance of carbohydrates in cellular respiration?

Back

Carbohydrates are broken down during cellular respiration to produce ATP, which provides energy for cellular activities.

Front

What are the stages of mitosis?

Back

The stages of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What is the function of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions by lowering the activation energy required.
