Question

Professor Danielle conducts an experiment on chloroplasts by deactivating several enzymes used for light-independent reactions. All components of light-independent reactions remain present. Would the light-dependent reactions proceed normally? Explain.
PLEASE HELP!!!!

Answer 1

Answer:

NO.

Explanation:

The process of reaction of CO2 with H20 in the presence of enzyme, chlorophyll and sunlight is called photosynthesis. It has two stages: It is referred to as light dependent stage when it occurs during the day and light independent stage when it occurs at night.

The primary enzyme likely to  be deactivated by the Professor is ribulose bisphosphate  Carboxylate Rubisco. This is the most important enzyme in plants that catalysis the fixation of Co2  with 5C- ribulose bisphosphate  Carboxylase (RuBP) to form3C -Glycerite -3-phospate.(GP).

The GP is reduced by NADP with ATP to form Triose Phosphate (TP). This is the point of glucose production in plants,

The majority of the TP is used for RuBP, hexose phosphates  for starch productions, fatty acid and glycerol for cell membrane.  Amino acids are also produced from TP. This is known s Calvin Cycle.

If the enzyme Rubisco is deactivated, the above process cannot occur, thus the basic macronutrients and enzymes  for the survival of plants for photosynthesis(light dependent stage)  can not occur.
