Chlorophyll converts solar energy into chemical energy
Answer:
<u>All the substrates are bound to the enzyme</u>, thats why the reaction rate stopped increasing.
Explanation:
Actually an enzyme works by binding a substrate molecule to its active site, producing a product , resulting in an increase in the rate of reaction.
Enzyme + substrate = Enzyme + product
Whenever enzymes are added , reaction rate increases as the substrates are being bound to the enzyme's active sites but then occurs a stage where further addition of enzyme cannot increase the reaction rate because all the substrates have bound to the enzyme and <u>there are no substrates left.</u> Hence the reaction rate stopped increasing.
Answer:
All viruses are obligate parasites; that is, they lack metabolic machinery of their own to generate energy or to synthesize proteins, so they depend on host cells to carry out these vital functions.
