Reactions between atoms occur when:
anyanavicka [17]

Answer:

A :an atom seeks to fill its outer shell of electrons

Explanation:

Reactions between atoms occur due the desire of an atom to fill their outer shell electrons.

The driving force for many interatomic bonding is the tendency to have completely filled outer energy levels like those of the noble gases.

  • The various interatomic interaction which leads to chemical reaction is in a bid for the atoms to be isoelectronic in the outer energy level with the noble gases.
  • This is achieved by gaining, losing or sharing of electrons.

Select all of the true statements regarding non‑shivering thermogenesis.
lora16 [44]

Answer:

a, b, d y e

Explanation:

We can define thermogenesis as the method of production of lime or temperature that a living body generates, in biology it is studied that this does not occur in all animals, but is seen in so-called warm blood and some plants, there are three types of processes identified in animals:

NEAT: defined as thermogenesis that occurs without the presence of physical activity

DIT: defined as the thermogenesis that occurs with physical activity

EAT: defined as the thermogenesis that occurs with the consumption of food or diet

Thermogenesis under the thermogenin protein found in brown adipose tissue produces a disengagement of protons within the mitochondria, prevents ATP synthesis and is capable of inducing temperature with the flow of protons, it also intervenes by increasing glycolysis, lipogenesis and gluconeogenesis with which its final result in these processes is the production of energy. The effect of the sympathetic nervous system and thyroid hormones that can balance heat production without generating abnormal movements such as tremor is also recognized.

Thus we deduce that:

electron transport allows heat flow without causing tremors

Thermogenin is involved in allowing protons to enter the mitochondria and the ATP production process is carried out.

hydrolysis of fatty acids occurs in the presence of norepinephrine

in brown adipocytes ATP synthase can be avoided

3) which statement most succinctly sums up the general function of an enzyme?
klemol [59]

Answer:

3) The correct answer would be the third option.

Enzymes are biocatalysts which increases the rate of a biochemical reaction is decreasing the activation energy required by the reaction.

The substrate binds to the active site of the enzyme to form an enzyme-substrate complex. It is then converted to enzyme-product complex. Lastly, the product is released and the enzyme is ready for a new cycle of reaction.

4) The correct answer would be cohesion.

Cohesion or cohesive force refers to the attractive force by which like-molecules are stick together.

For example, water molecules are stick together to form droplets.
