35. In the Calvin cycle, NADPH is: A) B) C) D) E) oxidized. reduced. phosphorylated. oxidized and reduced. None of the other answer options is correct. 36. The ATP generated by a photosynthetic electron transport chain can be used in the step(s) of the Calvin cycle. A) carboxylation B) reduction C) regeneration D) reduction and regeneration carboxylation, reduction, and regeneration 37. Photorespiration occurs because: A) B) C) D) E) there is more O2 than CO: in the atmosphere. rubisco is a slow catalyst. rubisco is a selective catalyst. there is more O2 than CO2and rubisco is a slow catalyst. there is more O: than CO2 and rubisco is a selective catalyst. 38. The products of the Calvin cycle are used to assemble larger sugars in the: A) stroma. B) matrix of the mitochondria. C) cytoplasm. D) mitochondrial intermembrane space. E) thylakoid lumen. 39. The process in which one cell takes up residence in another cell is called: A) commensalism. B) parasitism. C) endocytosis. D) exocytosis E) endosymbiosis.

Explanation / Answer

35 - NADPH in Calvin cycle donates its electron to reduce CO2. So NADPH is oxidized.

SO answer is the option A- Oxidize

36 - ATP helps in carbon dioxide fixation and reduction and regeneration

So the answer is the option E.

37 - Rubisco enzyme has the affinity both for CO2 and O2.

So the answer is option E.

38 - Synthesis of sugar takes place in the stroma.

So the answer is option A - stroma

39 - Parasitism is the relationship where one organism lives inside the host cell and obtained its nutrition

So the answer is an option B- parasitism

40- Endocrine is the cell signalling where one cell release hormone from one site and hormones reaches to the other cell via blood

So the answer is option C- endocrine

41 - Reactive oxygen species are very reactive species which can oxidize the membrane and harms the cell.

So the answer is option B.

42 - In animals glucose is stored in the form of glycogen and in plants, it is stored in the form of starch

So the answer is an option D.

43 - All the enzymes that are required for glycolysis are present in the cytoplasm. Glycolysis takes place in the cytoplasm

So the answer is option A.

44- A molecules that lose electron is said to be oxidized and the molecule that gains the electron is said to be reduced.

So the answer is option A.

45 - Reducing agents is a molecule or atom that lost the electron in turn itself get oxidizes.

So answer is option A.
