2. Summarize the events of the Calvin Cycle, highlighting thesignificance of following molecules in the metabolic pathway:Glucose Ribulose 1,5 bisphosphate (RuBP) ATP 3-phosphoglycerate(PG) NADPH Glyceraldehyde 3-phosphate (G3P) CO2.Student Answer: The Calvin cycle is a complex metabolic pathwaythat results in the production of glucose (and other sugars).Ribulose 1,5 bisphosphate can be thought of as the startingmaterial. Carbon dioxide is combined (fixed) with RuBP forming asix carbon molecule that is unstable and breaks down into3-phosphoglycerate (3PG). 3PG molecules are phosphorylated (haveenergy in the form of phosphate added to them from ATP) and reduced(by NADPH) producing Glyceraldehyde 3-phosphate (G3P) which isphosphorylated (has energy in the form of phosphate added to themfrom ATP) producing RuBP which is put together to make glucose.What grade would you give this student, 5 being the best? Explainyour reasoning.
Fill in the blanks below to complete the sentences about photosynthetic reactions within the chloroplast, and then order the sentences chronologically:
During the photosynthetic light reactions, clusters of pigments and proteins called photosystems absorb light and water and produce energy. The byproduct of this process is oxygen.
The Calvin cycle, also known as the light-independent reaction during photosynthesis, uses ATP and NADPH. It produces carbon dioxide and PGAL.

Q. 1. Order the events of photosynthesis from first to last: (4 Points)(a) Energy from excited photon used to generate ATP(b) Photon strikes chlorophyll molecule(c) NADPH is generated from NADP and H+(d) NADP+ and H+ reduce CO2 into carbohydrates
Q.2. Review the figure of Chloroplast below and label key structures and processes in the chloroplast of a plant cell using the following terms under two categories: Type of reactions – Light dependent or Light independent; and Substances – CO2, H2O, O2, Photons; Sugars. (6 points)
ChloroplastKey Structures:1. Thylakoid membrane2. Granum3. Stroma
Key Processes:Light dependent reactions:- Photons are absorbed by chlorophyll in the thylakoid membrane- ATP is generated through photophosphorylation- NADPH is generated through the transfer of electrons
Light independent reactions:- CO2 is fixed and converted into sugars through the Calvin cycle- Sugars are produced in the stroma
Put the following events of photosynthesis in order.1. Energy from ATP, electrons from NADPH, and a carbon compoundmade from fixation combine to form high energy G3P that can be usedto produce sugars2. high energy electrons are used to reduce NADP+ to NADPH3. Rubisco fixes a carbon from carbon dioxide to an organiccarbon compound4. Photon of sunlight strikes a pigment in photosystem 15. High energy electrons travel along a transport chain thatultimately leads to ATP production.6. Photon of sunlight strikes a pigment in photosystem 2
So here we are having a thing which is here: we are filling the blanks related to the photo synthesis, which is a step here, which is a process photosynthesis. So what is happening photo sentiments have 2 type of reaction, light reaction and a dark reaction. So what is happening, the light reaction, which is here the light reaction? It is here when the right reaction, it is boasted from the photo system to, and here it is a thing that is creating a gradient. So this is radiant, it is created and it will create a proton gradient, so proton gradient. It is created in the black 1 the proton gradient. It is our answer further, which is happening. It is needed to produce the a t p. It is used to…
