A student exposed two plants to only a red light and two plants only to green light. Which plants would grow better? Why?

The plants exposed to red light would grow better because green light would be reflected.



Explain how heterotrophs get their energy from the sun.

They have it from sugars, which is made from the Sun.

Where do the electrons moving along the inner membrane come from?

NADH

ATP synthase is an enzyme. What reaction does ATP synthase catalyze when an H+ ion passes through its channel?

Phosphorolation (ATP production)

Where do electrons moving along the inner membrane end up?

They are used to make water.

Suppose Priestley repeated his experiment using many kinds of plants besides mint, and that when different plants were placed under the jar the candle remained lighted for different periods of time. What would be a logical conclusion from these experiments?

Different plants release different amounts of oxygen.

What is not a step in the light-dependent reactions?

ATP and and NADPH are used to produce high energy sugars.

Glycolysis requires

an energy input

Why does the inside of the thylakoid membrane become positively charged during the light-dependent reactions?

Hydrogen ions are released as water splits.

What affects the rate of photosynthesis?

Temperature, light intensity, and water

The energy needed to win a 2-minute footrace is produced mostly by

Lactic acid fermentation

Cellular respiration releases energy by breaking down

food molecules

What is released during cellular respiration?

Energy

A student is collecting the gas given off from a plant in bright sunlight at a temperature of 27 degrees Farenheit. The gas being collected is probably

oxygen

Energy released from ATP when

A phosphate group is removed

The light dependent reactions supply the Calvin Cycle with

ATP and NADPH

If a plant and burning candle are placed under a bell jar, the candle will burn because

the plant gives off oxygen
