- Q1Which of the following is a PRODUCT of photosynthesis?OxygenChlorophyllCO2Water120s
- Q2Why is photosynthesis called a chemical pathway?Because it has a cycle.Because we like complicated answers.The products of one reaction are consumed in the next reaction.Because reactions occur.120s
- Q3In what organelle does photosynthesis occur?NucleusChloroplastMitochondriaCytoplasm120s
- Q4What happens when light hits either photosystem?ATP is created.Protons are pumped into the thylakoid.An electron becomes depressed.An electron becomes excited.120s
- Q5Chlorophyll b...absorbs green light.is the main pigment in plants.is an accessory pigment.120s
- Q6Which pigment is found in photosystems II and I.CarotenoidsStromaChlorophyll bChlorophyll a120s
- Q7Why doesn't photosystem II run out of electrons?Because it has infinite electrons.Because the plant splits water to get more.Because photosystem II gets electrons from CO2120s
- Q8How is ATP made?Protons leave the thylakoid through ATP Synthase.Protons enter the thylakoid through ATP Synthase.Sunlight excites electrons, which form ATP.Water splitting creates ATP.120s
- Q9How is NADPH formed?Protons leave the thylakoid.Water is split apart.An electron is attached to NADP+.Sunlight excites the NADP+.120s
- Q10Why are these called the light reactions?Because they need light to occur.Because they create light.Because they can not occur with light.Because they aren't as heavy.120s
- Q11Why do leaves look green?Because it's a pretty color.Because they reflect green light.Because they absorb green light.Because they don't feel well.120s
