Front

What happens to a protein/enzyme when it is denatured?

Back

It loses its structure and function, but denaturation can sometimes be reversible.

Front

How does pH affect hydrogen ion concentration?

Back

As pH increases, the hydrogen ion concentration decreases.

Front

What is the primary function of photosynthesis?

Back

To capture sunlight and produce sugars.

Front

Which macromolecule serves as enzymes?

Back

Proteins serve as enzymes.

Front

What is the Calvin Cycle?

Back

A step in photosynthesis that synthesizes G3P (glyceraldehyde-3-phosphate).

Front

What are the light reactions in photosynthesis?

Back

The first stage of photosynthesis that captures sunlight to produce ATP and NADPH.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell.

Front

Define enzyme specificity.

Back

Enzyme specificity refers to the ability of an enzyme to select and catalyze a specific substrate.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, substrate concentration, and enzyme concentration can all affect enzyme activity.

Front

What is the difference between competitive and non-competitive inhibition?

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while non-competitive inhibition occurs when an inhibitor binds to an allosteric site.
