Answer:

<h2>Liver </h2>

Explanation:

1. Glucagon: it control the glucose levels in the blood.

2. Glucagon is produced by the alpha cells, in the pancreas.

3. It prevent dropping of blood glucose levels too low. so, it acts on the liver in many ways:

4. It stimulates the breakdown of glycogen which is stored in the liver into glucose, which finally released into the bloodstream, this process is known as glycogenolysis.

5. It also stimulates the production of glucose from amino acid molecules and some other non carbohydrate pre-cursors, by the process known as gluconeogenesis.

TWO ways in which therapsids are different from reptiles.

Svet_ta [14]

Answer:

Therapsids were "mammal-like" reptiles and are ancestors to the mammals, including humans, found today. One group of therapsids is called dicynodonts. All species of dicynodonts were herbivores (plant eaters) and their sizes ranged from small burrowers to large browsers.

Mammals evolved from a group of reptiles called the synapsids. These reptiles arose during the Pennsylvanian Period (310 to 275 million years ago). It was over millions of years that some of these therapsids would evolve many features that would later be associated with mammals.

Many exergonic reactions fail to happen at a reasonable rate (e.g. conversion of diamonds to charcoal). This is due to the fact

Oksanka [162]

Answer:

The correct answer is "The free energy of the transition state is much higher than the free energy of the reactants".

Explanation:

Activation vitality is the base measure of vitality required to begin a concoction response. The wellspring of this initiation vitality is generally the warmth from the encompassing. An Enzyme builds the pace of a compound response by bringing down its actuation vitality.

During a compound response, new bonds are made and old ones are broken. Since the bonds are vitality putting away , this prompts arrival of vitality when broken, However, To get the particles into a state where their bonds can be broken, the atom ought to be mad. To accomplish this shape, Activation vitality is required, which is a high-vitality flimsy state.

Because of the above explanation, cells at time couple exergonic reaction(\DeltaG<0) with endergonic reaction(\DeltaG>0), permitting them to continue. This is known as vitality coupling and is unconstrained. At the point when the exergonic response discharges free vitality, consumed by the endergonic response.
