The high energy electron in photosystem II comes from whereas the high energy electron in photosystem I comes from___. oxygen, photosystem II photosystem I, water photosysytem I, oxygen water, photosystem II Rubisco is an enzyme in the: Calvin cycle, fixing carbon dioxide into carbohydrates. Kreb\'s cycle, releasing carbon dioxide from carbohydrates. light phase of photosynthesis, producing NADPH. mitochrondrial inner membrane, moving protons into the intermembrane space. Which is not a phase in the Calvin cycle? Carbon dioxide fixing B. production of glucose. formation of citric acid. replenish ribulose bisphosphate. Which of the following generates NADPH? photosystem I photosystem II Calvin cycle Kreb\'s cycle Spindle fibers attach to on the chromosomes. cohesin kinetochore centriole centromere A cell actively making protein through transcription and translation will have in its nucleus. cromosomes heterochrornatin euchromatin DNA and histones are components of: chromatin spindle fibers chiasmata cohesin The presence of two dominant alleles on a pair of chromosomes is called: heterozygous homozygous Which of the following is recessive homozygous?

Solution

17. D. Water, photosystem II

The electrons required during photosynthesis in photosystem II comes from photolysis of water, it passes through series of light harvesting molecules and finally reaches photosystem I.

18. A. Calvin cycle, fixing carbon di oxide into carbohydrates

During Calvin cycle Ribulose bisphosphate (RuBP, 5-Carbon sugar) and carbon dioxide condense to form first 6-Carbon sugar in a reaction catalysed by enzyme Rubisco.

19. C. Formation of citric acid

The citric acid formation is a part of Kreb
