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.
If the Calvin cycle slows down, THE RATE OF OXYGEN PRODUCTION IN PS II WILL BE REDUCED.
This is because, the light reaction depends on the dark reaction to occur. If the Calvin cycle slows down, the light cycle will have less ADP and NADP+ to work with and this will slow down the production rate of the photosynthetic reaction.
Glycogen is also called as the animal starch. This carbohydrate polymer is made up of the several repeating monomer units (in thousands) of alpha D glucose. The skeletal muscles break down this glycogen into the monomer alpha D glucose units in order to generate energy, which can be used for the contraction and relaxation of the muscle filaments.
Hence, the answer is 'alpha D glucose'.
