Which gender tends has higher BMR?

Basal metabolic rate

Men usually have a higher BMR than women since they tend to have more muscle. Older adults usually have a lower BMR than younger people since their muscle mass tends to decrease with age. The BMR accounts on average for about three quarters of an individual’s energy needs.

Does epinephrine increase basal metabolic rate?

Background: Epinephrine increases the metabolic rate and contributes to the hypermetabolic state in severe illness.

Which of the following increases the metabolic rate?

Thyroxine increases the number and activity of mitochondria in cells by binding to the cells’ DNA, increasing the basal metabolic rate. Administration of thyroid hormones, such as thyroxine, causes an increase in the rate of carbohydrate and fat metabolism and a rise in the rate of protein synthesis and breakdown.

Which group has the highest metabolic rate?

Hummingbirds, with their tiny bodies and high levels of activity, have the highest metabolic rates of any animals — roughly a dozen times that of a pigeon and a hundred times that of an elephant. To maintain those rates, hummers have to consume about their weight in nectar daily.
