ANSWER-37)
A is not correctly associated.
Explanation-
Fat is a form of chemical energy stored in body.
Muscles convert chemical energy to kinetic energy by movement.
Glucose is form of chemical energy which is utilized by body as fuel.
Water in Dam is an example of potential energy.
ATP is a form of chemical potential energy.
ANSWER-38) C -G2 phase
G2 phase is the second gap/growth phase. In this phase RNA and protein synthesis occurs, Formation of macromolecules, cell organelles also occur. In this phase synthesis of DNA stops. Cell prepares to undergo cell division. The second check point of cell cycle lies between G2 and M phase.
ANSWER-39) C -Carbon dioxide fixation.
Calvin cycle reduces CO2 to Glyceraldehyde -3-phosphate by using ATP and NADPH produced by Light reaction. Carbon fixation, reduction phase, carbohydrate formation, and regeneration phase are the four stages of Calvin cycle.
Calvin cycle starts with addition of molecule of CO2 to a five-carbon sugar, ribulose bisphosphate (RuBP). This reaction is catalyzed by Ru BP carboxylase or Rubisco. For every 3 molecules of CO2 6 molecules of G3P are produced, 5 of them are recycled to have a net of One G3P or Glyceraldehyde -3- phosphate.
ANSWER -40) D-The Citric acid cycle
Citric acid cycle is also known as Tricarboxylic acid cycle and Krebs cycle. One GTP (or ATP), three NADH, one FADH2 and two CO2 are produced in First round of Cycle. The cycle begins with the transfer of 2 carbon acetyl group from Acetyl CoA.

ANSWER-41) C-Golgi apparatus
Golgi apparatus gives rise to both lysosomes and vesicles. The main function of Golgi apparatus is modification, processing or packaging of proteins. IT helps in intracellular transport and trafficking.
--------------------------------------------------------------------------------------------------------------------
ANSWER-42) A
TT x tt will always display dominant genotype because all F1 progeny will have Tt genotype, which will have one dominant allele which will express dominant phenotype.
Tt X Tt = 3 dominant :1 recessive
tt X tt = ALL recessive.
Tt X tt = 2 dominant: 2 recessive.
---------------------------------------------------------------------------------------------------------------------
ANSWER-43) D , Oxidation of metabolite molecules and the corresponding reduction of coenzymes. Citric acid start by reacting oxaloacetate with Acetyl CoA forming Citric acid on which the cycle has been named. They reaction proceeds with a no. of rearrangements steps and generation of GTP, NADH, CO2 ,FADH2 . Oxaloacetate is regenerated at the end of cycle.
