Answer:

d. raise the apparent value of the equilibrium constant, L.

Explanation:

Allosteric regulation is a type of regulation of an enzyme by binding an effector molecule at a site other than the protein's active site (i.e., the allosteric site). The equilibrium constant (L) refers to the transition between two forms of an allosteric protein in absence of a ligand. The properties of allosteric enzymes are explained by conformational changes associated with a low-affinity tense (T) state, or a high-affinity relaxed (R) state. Negative allosteric effectors are molecules that bind to the allosteric site on an enzyme in order to decrease its activity, thereby leading the enzyme to a low activity T state and thus increasing the value of the equilibrium constant.

How does animals store energy
vovangra [49]

Animals ( or plants ) store solar energy as chemical energy between atoms of their molecules.

For example : ATP is phosphate energy bonds stored by animals in their molecules.

For more stable form animals also store energy in carbon bonds called carbohydrates. The most common e carbohydrates are starch, sugar and fats. Animals have enzymes to convert these forms of energy into actual form which they use for their activities like move, run or fly.

Scientists have found that extracellular matrix components may induce specific gene expression in embryonic tissues such as the
Romashka-Z-Leto [24]

Answer:

Integrins.

Explanation:

Integrins may be defined as the transmembrane ligand that activates the signal transduction pathway by binding with its receptor. Integrins is present in all animal cells.

Integrins helps in the direct communication of the cell with the extracellular matrix. The specific gene expression occur in liver and testes. Integrins are involved in the induction of the cell and their communication with the extracellular matrix.

Thus, the answer is integrin.

The major reason for bird species decline is loss of habitat, especially grasslands and forests. All have experienced declines in some areas since the 1960s and '70s, and further declines are anticipated, due to habitat loss and deforestation, and climate change

5. In Type 2 diabetes, the connection between insulin signaling and regulation of glycogen synthesis is lost. Select ONE ENZYME
ivann1987 [24]

Answer:

See blow

Explanation:

a and b) Metformine inhibits the enzime glycerol-3-phosphate dehydrogenase. This enzime catalyzes the conversion of glycerol phosphate to dihidrocetone phosphate. This decreases the concentration of NAD on the cytosol, and the realation NADH/NAD increases in this comparment, and decreases on the mitochondria, which restricts the conversion of lactate to pyruvate, preventing the use of the substracts to the gluconeogenesis.
