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

Because most cigar and pipe smokers do not ______, as a group they have a lower risk of cancer than cigarette smokers.
Artyom0805 [142]

Because most cigar and pipe smokers do not<u> </u><u>inhale the smoke</u> , as a group they have a lower risk of cancer than cigarette smokers.

The cigarettes, cigars, and pipe tobacco are made out of dried tobacco leaves. The other substances are usually added for flavor and to make smoking more gratifying. The smoke from these products is a complex mixture of chemicals produced by flaring tobacco and its additives.

There are at least 70 known chemicals to cause cancer. These cancer-causing chemicals are referred to as carcinogens.

It is so because cigars and pipes are usually believed to be less harmful way than to smoke tobacco. It was once a trend to use cigars in the 1990s, luring/dragging the young and the old.

Most of the people think cigars are less harmful to their health, but they actually pose the same risk for oral cancer as cigarettes do. Many cigar smokers don't inhale the smoke, but still the risk for oral, throat, and esophageal cancer is alike as for cigarette smokers.
