Solution

The correct option is A A-4 B-1 C-5 D-2 E-3
ATP The Adenosine triphosphate (ATP) molecule is the nucleotide known in biochemistry as the "molecular currency" of intracellular energy transfer; that is, ATP is able to store and transport chemical energy within cells. ATP also plays an important role in the synthesis of nucleic acids. Energy is released by hydrolysis of the third phosphate group. After this third phosphate group is released, the resulting ADP (adenosine diphosphate) can absorb energy and regain the group, thus regenerating an ATP molecule; this allows ATP to store energy like a rechargeable battery.
So the correct option is 'the currency of cellular energy'.
RuBisCo Ribulose-1,5-bisphosphate carboxylase/oxygenase, commonly known by the abbreviations Rubisco or rubisco is an enzyme involved in the first major step of carbon fixation, a process by which atmospheric carbon dioxide is converted by plants and other photosynthetic organisms to energy-rich molecules such as glucose. In chemical terms, it catalyzes the carboxylation of ribulose-1,5-bisphosphate (also known as RuBP). It is probably the most abundant enzyme on Earth.
So the correct option is 'huge enzyme complex that brings CO2 and a 5 carbon sugar together'.
RuBP RuBP stands for ribulose bisphosphate, it's a 5 carbon compound involved in the Calvin cycle, which is part of the light independent reactions of photosynthesis. Atmospheric CO2 is combined with RuBP to form a 6 carbon compound, with the help of an enzyme (biological catalyst) called RuBisCo.
So the correct option is 'the 5 carbon sugar that fixes CO2 in the calvin cycle'.
Glucose The oxidation of glucose contributes to a series of complex biochemical reactions which provides the energy needed by cells. The first step in the breakdown of glucose in all cells is glycolysis, producing pyruvate which is the starting point for all other processes in cellular respiration. In cells where oxygen is present (aerobic respiration) these processes have been modeled in the TCA or Krebs cycle. A major part of the use of the energy from glucose oxidation is the conversion of ADP to ATP, with the energy-rich molecule ATP being subsequently used as the energy currency of the cell.
So the correct option is 'product of calvin cycle'.
3-phosphoglyceric acid 3-Phosphoglyceric acid (3PG) is the conjugate acid of glycerate 3-phosphate (GP). The glycerate is a biochemically significant metabolic intermediate in both glycolysis and the Calvin cycle. This anion is often termed PGA when referring to the Calvin cycle. In the Calvin cycle, 3-phosphoglycerate is the product of the spontaneous scission of an unstable 6-carbon intermediate formed upon CO2 fixation. Thus, two equivalents of 3-phosphoglycerate are produced for each molecule of CO2 that is fixed.
So the correct option 'three carbon sugar that gives the nickname of calvin cycle'.
