The larger value obtained when more glucose carriers were present corresponds to an increase in the rate of glucose transport. E

Gekata [30.6K]

Answer:

Prediction is correct.

Explanation:

In the body, transportation of molecules can occur in different ways or mechanism.

An example is by facilitated diffusion.

It is a passive form of transport where carrier proteins shuttle the molecule such as glucose into the cell without using energy.

Glucose being a large molecule is shuttled by glucose carriers across the cell membrane into the cell by facilitated diffusion.

Therefore an increase in the number of glucose carrier means an increase in the rate of glucose transport.

The results will show our prediction was correct.

Use the Harris-Benedict equation to estimate your calorie needs. Show your calculations to explain how you arrived at your answe

Ratling [72]

Answer:

The Harris Benedict Equation is a formula that determines the total daily energy expenditure (calories) using BMR with some activity factors.

Basal Metabolic Rate (BMR) is defined as the amount of calories one would burn without doing anything for 24 hours. It uses variables of weight, age, height and gender to calculate BMR.

BMR calculation = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)

In Harris Benedict Equation, BMR is multiplied by activity factor to determine calories need.

The activity factors in Harris Benedict Equation are:

for no exercise = 1.2

exercise for 1 to 3 days/week or light exercise = 1.375

exercise for 3-5 days/week or moderate exercise = 1.55

exercise for 6-7 days a week or hard exercise = 1.725

exercise for 2 times training = 1.9

So, calculation for my calorie needs is as following:

BMR = 447.593 + (9.247 x 50 kg) + (3.098 x 164.592 cm) - (4.330 x 23 in years) = 974.945

Calorie needs = BMR x 1.55

= 974.945 x 1.55

= 1511.16 calories
