Question

ATP (ADENOSINETRIOHOSPHATE) HAS BEEN CALLED THE ENERGY CURRENCY OF THE CELL. BRIEFLY OUTLINE THE CYCLE BY WHICH ENERGY IS STORED IN AND RELEASED FORM ATP. DISCUSS HOW ATP IS CRITICALLY IMPORTANT TO CELLULAR PROCESSES.

ENZYMES ARE PROTEIN MATERIALS THAT CONTROL CHEMICAL PROCESSES. DESCRIBE THE SPECIFIC MECHANISMS F ENZYME FUNCTION. PICK A SPECIFIC ENZYME AND DESCRIBE ITS FUNCTION AND THE IMPORTANCE OF THAT FUNCTION TO LIFE. DISCUSS HOW THE LOSS OF THAT ENZYME WOULD DISRUPT LIVING PROCESSES. MAKE SURE YOUR EXPLANATION OF ENZYMES IS IN FORMED BY THE TEXTBOOK.

Answer 1

ATP molecule stored energy in the form of high energy phosphate bond which joins the terminal phosphate group.In this form the energy can be stored in this form in the cell at one location but whenever the energy is needed high energy phosphate bond is broken and drives the metabolism of other biochemical reaction. when iorganic phosphate is released , it results the liberation of 7.3 Kcal/mol.

For example glycogen phosphorylase is an enzyme which catalyze the breakdown of glycogen into glucose-1-phosphate under the regulation of glucagon hormone. when cell need glucose this enzyme breaks glucose into its monomer. Loss of this enzymes critically affects the normal metabolism of glycogen and hampering the function of this enzymes leads to the death of cell and diseased condition.
