Term
what is the effect of body size/BMR on weekly food requirements? |
|
Definition
proportionate to their weight, small animals eat WAY more than larger animals to accomodate their high metabolic rates |
|
|
Term
|
Definition

|
|
Term
why does metabolic rate increase with body temp? |
|
Definition
more kinetic enercy increase the chance of substrates hitting enzymes
higher energy molecules more frequently collide and with greater force than low energy molecules.

|
Definition
it deacreases the metabolic rate to save energy |
