QUESTION 4 You have been tasked to cultivate a type of plant for horticulture. Inexperience as you are, you have tried to grow the plant in a massive number in a greenhouse. Among the plants, you noticed a stunted plant and decide to investigate it. In your investigation, you discovered the stunted plant have a rare form of mutation that are producing a mutated, malfunctioning form of an enzyme that responsible for the formation of sucrose. Equipped with what you have learnt about plants, analyse in detail why the plant growth was hindered while taking consideration with the relationships between tissues of plants.

QUESTION 10 A) In glycolysis, the glucose which has 6 carbon molecules is eventually broken down into 2 molecules of 3 carbon compounds as pyruvate. Regardless of all the enzymes involved, describe the key points that change the 6 carbon compound into two molecules of 3 carbon compound. B) As glycolysis splits glucose into two pyruvate molecules, the link reaction occurs twice per molecule of glucose. Briefly explain the process after pyruvate transported from the cytosol into the mitochondrial matrix.
