what percent of the body’s glucose is used by the brain?

Answers

Answer 1

Explanation:

In humans, the brain accounts for ~2% of the body weight, but it consumes ~20% of glucose-derived energy making it the main consumer of glucose (~5.6 mg glucose per 100 g human brain tissue per minute.

Answer 2

Generally, the brain uses 20% of the total glucose in the body. The reason behind this is that glucose is primarily used by the brain. Glucose can pass the blood-brain barrier.

How is glucose used by the body?

Generally any individual takes Dietary Carbohydrates. Most of these Carbohydrates are polysaccharides in nature such as starch etc. Disaccharide such as sucrose, galactose are taken by organisms too. These large molecules, or macromolecules, are digested by the stomach and intestine and absorbed by cells. Glucose is taken up by the cell and undergoes glycolysis to produce ATP. It doesn't require oxygen, so it can take place in almost all cells of the body.

Glucose is taken up by the brain as it can pass the blood-brain barrier. Proteins and lipids can't cross the blood-brain barrier like glucose. There are many functions that take place in the brain, so it needs frequent energy. About 20% is consumed by brain. This energy can be derived from glucose.

Hence, about 20% of the glucose is used by the brain for several functions.

how many days a week you need to work out to notice a difference

Answers

Answer:

every other day to a day but don't strain your muscles

Explanation:

Brenna's mother recently fell down the lowest step of their front porch while scooping snow, and she cracked her ulna. Brenna gets angry at her mother for scooping the snow in the first place when she knows she has osteoporosis and a tendency for falling. Brett hires a snow removal service that will arrive as early as possible after future snows to prevent this from happening again, because they both know that Brenna's mom is going to continue to shovel. She still feels young, and she says her osteoporosis and age aren't holding her back in life.

Brenna and Brett both feel that even though Brenna's mother has a history of falling every couple of years, she is overall very healthy compared to others her age. Brett's mom on the other hand is only a few years older and very active in her local community organizations and tennis league.

Functional status is a better indicator of health in older adults than age, because how they have taken care of themselves over their lifetime greatly affects how they feel and function. Two different 70-year-olds can have completely different health statuses.

a. True
b. False

Answers

The statement 'two different 70-year-olds can have completely different health statuses' is TRUE. Health is a result of both environmental and genetic factors instead of only age.

Health is a physical and mental condition of well-being by which a person can develop his/her maximum potential.

The aging of a person is a process that occurs in an independent mode of different physiological pathways (e.g., maintenance, repair, defense).

In consequence, although aging is often associated with different diseases, aging in itself is not a disability/disease condition, thereby a person may have 70 years old and exhibit excellent physical/mental conditions.

why do fat-soluble vitamins need to be consumed less frequently than water-soluble vitamins?

Answers

Answer:

While vitamins are essential nutrients our bodies require to function properly, many of us get what we need through our diet.

Water-soluble vitamins are those that are soluble in water. They are stored in small quantities and, therefore, it is necessary to ingest them daily. Fat-soluble vitamins, on the other hand, are those soluble in lipids.

What are fat-soluble and water-soluble vitamins?

“For fat-soluble substances to be absorbed, the presence of bile and pancreatic sulcus, in addition to lipids, is also necessary. They are vitamins A, D, E and K. The water-soluble vitamins are all the vitamins of the B complex and vitamin C.

With this information, we can conclude that water-soluble vitamins are those that are soluble in water. They are stored in small amounts and therefore it is necessary to eat them daily. Fat-soluble vitamins, on the other hand, are those soluble in lipids.
