In oxidative phosphorylation, which of the following terminally accepts the electron? -
Answer-oxygen
The second part of photosynthesis, the so called DARK reactions (Calvin-ycle) occur in

produced in mitochondria

to make high-energy electrons, which are transferred by an electron-transport chain.
Where are the protein complexes of the electron-transport chain located in
chloroplasts? - Answer-thylakoid membrane
Photosynthesis is COMPLEMENTARY to respiration (glycolysis + TCA cycle + oxidative
phosphorylation) in many ways. Which of the following statements is NOT TRUE? -
Answer-photosynthesis CONSUMES one glucose and six oxygen molecules, releasing
six carbon dioxide and six water molecules while respiration REQUIRES the input of six
carbon dioxide and six water molecules producing one glucose
Photosynthesis in plants uses electrons from water to reduce? - Answer-carbon dioxide
with consumption of ATP and NADPH
The second part of photosynthesis, often referred to as the DARK reactions, involves
the reduction of CO2 to synthesize organic compounds such as 3-phosphoglycerate
and sucrose. What cofactor is the electron donor for carbon fixation (CO2 reduction)? -
Answer-NADPH
Glucose is imported into cells by glucose transporters and glucose levels inside cells
are constantly regulated. What prevents glucose of being exported towards the outside
of the cell when glucose levels on the inside are high? - Answer-upon intake, glucose is
immediately phosphorylated by hexokinase
Anabolic and catabolic are opposing in which ways? Select the statement that IS NOT
TRUE. - Answer-food molecules feed anabolism while macromeolecules are
synthesized by catabolism
In which ways is gluconeogenesis the reverse of glycolysis. Which of the following IS
NOT TRUE? - Answer-gluconeogenesis produces pyruvate and glycolysis makes
glucose
