Unit 3 Review

Front

What pigment is more favorable in green light?

Back

Pigment A (Graph I) is more favorable in green light.

Front

Was Earth's atmosphere oxygenated when it first formed?

Back

False. Earth's atmosphere was not oxygenated when it first formed.

Front

Which step of photosynthesis occurs in the stroma?

Back

The Calvin Cycle takes place in the stroma.

Front

Does any increase in heat denature an enzyme?

Back

False. Not every increase in heat will denature an enzyme; it depends on the enzyme's specific temperature range.

Front

Which substrate does the enzyme catalyze?

Back

The enzyme catalyzes substrate Δ.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths, and converts it into chemical energy.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the Light Reactions and the Calvin Cycle.

Front

What is the primary function of the Calvin Cycle?

Back

The primary function of the Calvin Cycle is to convert carbon dioxide and other compounds into glucose.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to external stress, such as heat or pH changes.

Front

What factors can affect enzyme activity?

Back

Factors that can affect enzyme activity include temperature, pH, substrate concentration, and enzyme concentration.
