Cellular Respiration and Metabolic Rates

Question 1

Metabolic Rate

Answer 1

The sum of all chemical reactions occuring over a period of time per amount of body weight.

Question 2

Ectothermic Animal

Answer 2

Is one that obtains most of its body heat form the surrounding environment.

Question 3

The metabolic rate of an ectothermic animal doubles with every ___ increases in body temperature

Answer 3

10° C

Question 4

Body Temperature Equation

Answer 4

Body Temperature (BODY HEAT) = 
heat produced (BY METABOLISM) + 
heat gained-heat lost (to and from the environment)

Question 5

The modes of heat loss or heat gain include what?

Answer 5

radiation, conduction, convection and evaporative cooling.

Question 6

Radiation

Answer 6

The emission of energy by all objects warmer than absolute zero.

Question 7

Conduction

Answer 7

Heat loss or gain through direct contact with solid objects

Question 8

Convection

Answer 8

Heat loss or gain due to wind and water currents.

Question 9

Evaporative Cooling

Answer 9

The loss of heat when a liquid evaporates into a gas.

Question 10

Endothermic Animal

Answer 10

An animal that obtains most of its body heat from its own metabolism.

Question 11

Endothermic animals maintain consistently warm body temperature because of what?

Answer 11

Due to large amounts of cellular respiration taking place.
