Sprint LTE 9:02 PMM Student Email b) Citric acid cycle c) Electron transport chain (Oxidative phosphorylation) d) All of the above produce the same amount of ATP 22. Which stage of the mitotic phase is represented by the picture below? a) prophase b) prometaphase c) metaphase d) anaphase e) telophase 23. Glycolysis is a metabolic pathway in which a glucose molecule is broken down into two pyruvate molecules, therefore glycolysis is: a) a catabolic pathway b) an anabolic pathway c) an amphibolic pathway d) none of the above 24. In photosynthesis, the enzyme RUBISCO performs the addition of a CO, molecule to a soluble organic, this step is called carbon fixation and it occurs a) during the light-dependent reactions in the thylakoids b) during the light-independent reactions in the thylakoids c) during the light dependent reactions in the stroma d) during the light-independent reaction in the stroma 25. Which of the following metabolic pathway is anabolic? a) Fermentation b) Cellular respiration c) Photosynthesis d) All of the above

Explanation / Answer

Answer:

22). D). Anaphase

Explanation: During anaphase, chromosomes split into two chromatids and the chromatids move to opposite poles.

23). A). A catabolic pathway

Explanation:

The term amphibolic is used to describe a biochemical pathway that involves both catabolism and anabolism. This term used to emphasise the dual metabolic role of such pathway. The citric acid cycle (The Krebs Cycle) is a good example of amphibolic pathway.

24). D). during the light-independent reaction in the stroma

Explanation: Cabon fixation is light-independent reaction and it occurs in the strom of chloroplast.

25). C). Photosynthesis

Explanation: Synthesis of large complex molecules from simple small molecules is called anabolic reaction.
