Which process involves chlorophyll in the thylakiod membranes absorbing solar energy?
Light reactions
True or False? Rubisco is an enzyme that can use both carbon dioxide and oxygen as substrates?
True
Which of the following organelles are found in both plant and animal cells?
Mitochondria
Which of the following parts of the electron transport chain are actually involved with moving protons (H+) across the thylakiod membrane to fill the thylakiod space?
Cytochrome b6f
plastoquinone
Vascular tissue found in plants that conducts water and minerals from the soil to the rest of the plant?
Xylem
Where does photosynthesis occur?
Chloroplast
True or False? C4 plants close their stomata to save water, but this causes them to not have photosynthesis when their stomata are closed.
True
Only the light reactions of photosynthesis convert solar energy into____________?
