When a virus attacks a cell, it kills the cell and the virus multiplies to spread throughout the body
Answer:
Photosystems is a process in which solar energy is converted into chemical which occurs in protein complex. There are two photosystems i. e. photosystem l and photosystem ll. Photosystem occurs outside surface of thylakoid membrane of chloroplast. In photosystem l, solar energy is converted into ATP and NADPH. Photosystem occurs inside surface of thylakoid membrane of chloroplast. In photosystem ll, hydrogen is extracted from water molecule which is used in the formation of ATP by using ATP synthase enzyme.
