Indicate if the following statements are true or false for the diagram:
1. The diagram includes both systems.
2. The diagram represents the dark reactions.
3. The green circles inside the photosystems represent pigments.
4. In the first electron transport chain, NADPH is produced.
5. In these reactions sugars are produced.
For the following questions, choose one to discuss: chloroplast/photosynthesis State at the outset which one you will discuss.
A) What role do proton gradients play in the process of photosynthesis proton gradients allow
B) Where are proton gradients formed? Within what structures are they seen in chloroplasts How do the structures help them to maintain a gradient?
C) Explain where and how the chloroplast or mitochondria uses passive transport and active transport to complete photosynthesis or cellular respiration.

- What are the stages of the Calvin-Benson cycle? Select all that apply. The resulting unstable six-carbon molecule splits into two three-carbon molecules of PGA. ATP and NADPH are used to convert PGA molecules to PGAL. Most of the PGAL is used to regenerate RuBP, but some is exported to the cytoplasm to produce carbohydrates. Rubisco attaches CO2 to a five-carbon organic compound called RuBP. Rubisco is used to convert PGA molecules to PGAL.arrow_forwardMAKE CONNECTIONS Explain how nitrogen andphosphorus, the nutrients that most often limit primaryproduction, are necessary for the Calvin cycle to functionin photosynthesis (see Concept 10.3).arrow_forwardPlease answer this question with proper elaboration.arrow_forward
