Digestive system Flashcards
what are the two types of reactions in the metabolism
-catabolic
-anabolic
metabolic pathways that
break down molecules into smaller units to
either release energy or for use in anabolic
reactions
catabolic
metabolic pathways that
construct macromolecules like DNA from
smaller subunits
anabolic
Occurs in the cytosol of
the cell
* Results in:
* Pyruvate x2
* ATP x2
* NADH x2
* Pyruvate can be
fermented into lactic acid
anerobic metabolism
Occurs in the mitochondria
* Puts pyruvate through the
Citric Acid Cycle
* Results in:
* NADH
* FADH2
* Electron transport chain
produces:
* ~ATP x32
* Water
aerobic metabolism
-the overall rate of an animals energy use
-Measured by how much oxygen the animal consumes within a given amount of time
* C6H12O6 + 6O2 ⟶ 6H2O + 6CO2 + ATP
metabolic rate
Oxygen demand is dependent on________-
activity level and body mass
elevated rate of oxygen
consumption following
activity
recovery metabolism
Energy Intake vs. Energy Use over a given period of time
energy balance
those amino
acids that an organism cannot synthesize
from others that they consume
* Which vary from species to species
* Most animals can synthesize about
half of their amino acid
essential amino acids
allows animal to
strain suspended food particles from water
suspension filter feeding
– allows animal to change
environmental pressure to force food into
mouth
suction feeding
joint that
connects the lower jaw to the skull
* Allows food to be mechanically
broken down before being swallowed
temporomandibular joint
types of teeth
-incisors
-canines
-premolars and molars
specialized for biting
incisors
