Answer:

A. The complementary shapes of an enzyme and a substrate

Explanation:

The Lock-and-Key model was made to show how an enzyme's active zone fits a substrate and how they bond together. It correlates just like a lock and a key; you have to have the correct-shaped key in order to open a lock. Same process of thought with the enzymes; you must have the same shape for both in order to bind together,

strojnjashka [21]

The answer is  Lionfish are native to the tropical Pacific. There are no natural water routes of warm water between the Pacific and Atlantic oceans.

Invasive species is a species that colonizes an environment in which it is not a native species and tends to upset the natural balance of that environment. Lionfish are naturally found in the indo-pacific, which is their native environment. However, their presence in the eastern United States has have threatened the ecosystem of the region. The fish has decimated fisheries and reef ecosystem since they also don’t have natural predators in the region. Therefore, their population explodes unchecked.

When the protein gramicidin is integrated into a membrane, an H+ channel forms and the membrane becomes very permeable to proton
Naddika [18.5K]

Answer:

The electron transport chain may be defined as the sequential steps of the oxidation and reduction of the cytochromes. The electron transport chain is important for the production of ATP.

The gramicidn protein is an ionophoric antibiotic that can affect the electron transport system. The electron transport rate, oxygen uptake and proton pumping remains the same as more hydrogen ions will enter in the cell.  But the ATP synthesis rate might decrease and completely stop by using gramicidin.

What would happen if our bodies could not metabolize glucose
Reika [66]

Answer:

The body can still get glucose from food, but the glucose can't get into the cells, where it's needed, and glucose stays in the blood. This makes the blood sugar level very high. ... When this happens, it may no longer be able to produce enough insulin to keep blood sugar levels where they should be.
