A 22g field mouse consumed 5g of mouse chow that had an energy content of 2Cal/g in 24hours and during that time produced urine and feces with an energy content of 6Cal. a. What was the amount of energy that the mouse used that day? b. What is the field mouse’ mass specific metabolic rate in J/g*hr? c. If the mouse gained a gram of body mass over that same day would the metabolic rate calculated be an underestimation or overestimation? Why?

A 22g field mouse consumed 5g of mouse chow that had an energy content of 2Cal/g in 24hours and
during that time produced urine and feces with an energy content of 6Cal.
a. What was the amount of energy that the mouse used that day?
b. What is the field mouse’ mass specific metabolic rate in J/g*hr?
c. If the mouse gained a gram of body mass over that same day would the metabolic rate
calculated be an underestimation or overestimation? Why?

Expert Solution
Step 1

Energy production is the basic mechanism in the living cell. ATP (adenosine triphosphate) is the energy currency for the living beings. The burning of glucose produces energy and oxygen. Energy is fixed in the plans by utilizing chlorophyll and sunlight. Plants store energy in the form of starch and other sugars.
