What are the 3 factors that affect an animal’s metabolic rate?

If such future studies yield results similar to those of our study, then three factors may largely account for the enormous range of species variation in metabolic rate: body mass, higher-level taxonomic affiliation, and the conditions of environmental productivity or food availability under which an animal has evolved …

What causes metabolic rate to increase?

Hormones: Thyroxine increases the metabolic rate of the whole body by increasing the rates of activity of almost all chemical reactions. Growth hormone and testosterone increase the metabolic rate by increasing basal metabolic rate.

What is BMR and factors affecting BMR?

Factors Influencing BMR:

There are many factors that affect the BMR. These include body temperature, age, sex, race, emotional state, climate and circulating levels of hormones like catecholamine’s (epinephrine and norepinephrine) and those secreted by the thyroid gland.

Which factor Cannot directly affect the rate of metabolism?

Age and gender are the factors affecting metabolism that you cannot control.

How does size affect metabolic rate?

As a general rule, the greater the mass of an organism the higher that organism’s metabolic rate is. … However, BMR is higher per unit of body mass in small animals compared to larger ones. This is because the higher metabolic rate of small animals needs a greater delivery of oxygen to tissues around the body.

Does higher body temperature mean higher metabolism?

It has been known since early in the 20th century that a rise in temperature is associated with an increase in metabolic rate. Each degree C rise in temperature is associated with a 10–13% increment in oxygen consumption (18). The elevation in temperature itself is responsible for speeding up metabolism.

What does my BMR mean?

Basal metabolic rate (BMR).

BMR is the number of calories your body uses to maintain vital functions, such as breathing, heart rate, and brain function.

Which factor is most important for drug metabolism?

Factors that affect drug metabolism

The Cytochrome P450 monooxygenase system is the most important pathway in this regard. In general, anything that increases the rate of metabolism (e.g., enzyme induction) of a pharmacologically active metabolite will decrease the duration and intensity of the drug action.
