Answer:
the binding of the substrate changes the shape of the enzyme's active site
Explanation:
According to induced fit theory, binding of substrate to the active site of the enzyme causes a conformational change in enzyme. This is referred to as the induced-fit mechanism and was postulated by Daniel Koshland in 1958. The induced fit brings specific functional groups on the active site of the enzyme into the proper position to catalyze the reaction and thereby enhances the catalytic activity of the enzyme. The induced conformational change facilitates the formation of additional weak interactions in the transition state.
Answer:
A) to increase the production of ATP
Explanation:
Brown fat cells have numerous mitochodria that have the uncoupling protein 1 (UCP-1). This protein is used to dissipate the proton-motive force generating heat (becomes important during cold temperatures) and uncoupling oxidative phosphorylation.
The statement that best explains the reason for the general trend in hominid evolution that occurred over millions of years is that; Hominids evolved to walk upright on their hind limbs, reducing the need for opposable toes. Hominids are the members of the family Hominidae; which includes humans and the great apes. There has been a continuous evolution in this class from the first hominids to the current human, which has seen a lot of change from the foot, the brain capacity, activities involved, among other features.
<span>This is turgor pressure. This is the mechanism by which a plant and its cell walls can maintain its rigidity. The movement of water between the cell walls and the inside of the plant allows for pressure to build up due to this diffusion, leading to a stiffness on the part of the plant.</span>
Answer:
human activity
Explanation:
The wetlands and the coral reefs have gradually been destroyed by the humans and their activity. The wetlands were the first to be under the human influence and getting destroyed, while the coral reefs have come to have similar destiny in the last century. The reasons for the destruction are different. The wetlands have in general been destroyed on purpose, be it because they were epicenter of diseases, for making more land for agriculture, or making more land for settlements. The coral reefs have not been destroyed on purpose, but the human activity has resulted in lot of pollution of the ocean waters, as well as changes in the climate, and the fragile corals can not adapt quickly enough to these changes, so they die out quickly.
