True b. False a. 5 G3P molecules go to form glucose and 1 G3P mole cule go to regenerate RuBP PagExplanation / Answer
Answer-11
(b)- phosphate transfer between organic molecule.
Answer-12
(b)- glycolysis is less efficient in producing ATP (i.e net gain in ATP is 8) than ETC or TCA (i.e net gain in ATP is 24)
Answer-13
(b)- coenzyme i.e. all are reducing agent
Answer-14
(d)- ATP-energy provides by coupling endergonic reaction to ATP
Answer-15
(d) a & b
Answer-16
(b)- gain, loss
Answer-17
(c)-Cell-to-cell communication via plasmodesmata
Answer-18
(e)-all of the above
Answer-19
(c)- lactic acid found in Cori cycle
Answer-20
(d)-all of the above
Answer-21
(b)-false; 3PGA first converts into 1,3-bisphosphoglycerate and than into G3P
