Answer:
Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.
Answer:
D (or E If properly listed to include the active site option)
Explanation:
A. Is true
Enzymes are organically biochemical catalyst and thus they can speed up the rate of chemical reaction in the body
B is true
They are catalysts as said earlier
C is true
They have active sites. An enzyme does not act on all substrates. They have particular group on which they can act. For example, we have carbohydrates enzymes that act on carbohydrates substrate only. This enzymes have no business acting on a protein substrate.
D. Enzymes are proteins
One of the important characteristics of enzymes is that they are protenious in nature
E. This is wrong. Enzymes like any over catalyst are not consumed in the course of the biochemical reaction

<span>It is true that energy efficient dishwasher is a water
and energy saver than washing dishes by hand. A star-rated dishwasher uses 4
gallons of water in each cycle compare to a kitchen faucets who pumps out 2.5
gallons of water per minute. To conserve water, the accumulated dishes and cookware
must be stack properly in a dishwasher before running a cycle. As to conservation
of energy, people tend to use warm water to wash the dishes by hand and heating
of water cost much, while in a dishwasher, energy-saving tips such as running a
light cycle and turning off heating drying option will mark down your energy
consumption. Therefore, the use of dishwasher is a much greener idea. </span>
