Explanation / 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

Answer-22
