Why are green leaves green?

Chlorophyll reflects green light

Chlorophyll absorbs green light

Chlorophyll absorbs blue and green light

When oxygen is released as a result of photosynthesis, it is a direct by-product of

electron transfer in photosystem II and I

ATP Synthase depends on

High concentrations of H+ in the thylakoid using passive transport to provide energy to make ATP to power the Calvin Cycle

Low concentrations of H+ in the thylakoid using passive transport to provide energy to make ATP to power the Calvin Cycle

High concentrations of H+ in the thylakoid using active transport to provide energy to make ATP to power the Calvin Cycle

Low concentrations of H+ in the thylakoid using active transport to provide energy to make ATP to power the Calvin Cycle

Thylakoids contain clusters of chlorophyll and proteins known as ______________________ . They absorb sunlight and generate high-energy ___________________ that pass along the _____________________.

photosystems, electrons, electron transport chain

chloroplasts, oxygen atoms, outer membrane

photosynthesis, protons, photosystem chain

stroma, sodium ions, oxygen receptor

The thylakoid membrane contains a protein called ATP synthase. As hydrogen ions pass through the protein, ADP and a phosphate group are combined to form ATP. What is the direct energy source, if any, for the movement of hydrogen ions and the formation of ATP?

The energy source is the concentration difference of hydrogen ions across the membrane.

The energy source is the high-energy electrons that accompany the hydrogen ions.

The energy source is a set of ATP molecules that gather inside the thylakoid.

There is no energy source; the process occurs without an energy input.

Although animals do not perform photosynthesis, their food supply depends on the sugars that photosynthesis produces. What is the other significant benefit to animals that photosynthesis provides?

adding oxygen to the atmosphere

removing water from the environment

adding carbon dioxide to the atmosphere
