Cellular Respiration Gerbil Metabolism - Science Learning Center

• The more energy gerbil consumes, the more oxygen he’s going to
consume, the more CO 2 he’s going to make.
• All reactions in cellular respiration result in some energy being lost
in the form of heat, and disrupted though out the environment.
Anatomical adaptations, these new innovations reduce heat loss
across the body, for example, fur, hair, feathers, these things are
use for insulation.
• a) Homeotherm (Endotherm): Warm blooded such as humans,
birds, mammals.
• b) Polklotherm (Ectotherm): Unable to maintain constant
internal body temperature. Body temperatures will fluctuate as
the environmental temperature fluctuates.
• The rate of CR (metabolic rate) can be determine by measuring
either the rate of consumption of raw materials (glucose or
oxygen) or production of end products CO 2 or water.
