AnswerAnswer 24: Option(D) is correct Explanation: The cell cycle is divided in to two phase as 1. Interphase( consist of G1, S and G2 Phase) 2. Mitotic phase As we know the interphase is very active phase in the cell cycle . We also call it as preparatory phase for cell to divide in a proper manner in Mitotic phase. The main action of interphase is the replication of DNA which takes place in Synthetic phase(S phase). Replication of DNA is very important before Mitotic phase so as to maintain the complete information of DNA. Answer 25: Option(C) is correct
Explanation: Basically we take energy from the food stuff which is present in food that we eat. All the food stuff contain bonds. When we eat food so by the process of catabolism the bond in food stuff is broken to convert the food energy in to usable form . But the form of energy which is basically used by cellular activity is the ATP. So we can say that it is basically the intermediate compound for cellular processes. hen bond of ATP is broken in presence of water so inorganic phosphate is formed by the release of 7.3K Cal / Mol of energy .
