C  substrate inhibition, catabolism, and fermentation

D  hydrolysis, active transport, and the light reactions

E  None of the above is correct.

A  pancreas

B  salivary glands

C  stomach

D  liver 

A  break down food chemically.

B  break down food physically.

C  carry food to the stomach. 

D  prepare undigested material and waste for disposal.

A  We must process nutrients in order to absorb them. 

B  The human gut is able to absorb complex proteins easily.

C  We are able to directly absorb most large nutrient molecules such as starch.

D  The absorptive surface of our gut lets all materials pass through it into the bloodstream.

A  The exit of the digestive system, known as the urinary tract, is needed to get rid of liquids you don’t digest.

B  Digestion increases the volume of food that initially enters the body.

C  Not all that you ingest is digested and absorbed, this “leftover” must be eliminated. 

D  You always eat more food than you need.

E  None of the above are correct.

A  is contained in matter placed in certain positions or arrangements. 

B  is kinetic energy that has not yet been turned to heat.

C  transfers motion to matter.

D  contains less energy than kinetic energy.

E  is stored energy unavailable to do work.

A  the alveoli

B  the bronchioles

C  the tracheoles

D  the trachea 

A  Oxygen is moved by active transport from the lungs to the deoxygenated (“used”) blood in the capillary beds, and carbon dioxide diffuses from the blood to the alveoli.

B  Carbon dioxide diffuses from the air into the deoxygenated (“used”) blood in the capillary beds, and oxygen diffuses from the blood to the alveoli.

C  Oxygen is moved by active transport from the lungs to the deoxygenated (“used”) blood in the capillary beds, and carbon dioxide is moved by active transport from the blood to the alveoli. 

D  Carbon dioxide is moved by active transport from the lungs to the deoxygenated (“used”) blood in the capillary beds, and oxygen diffuses from the blood to the alveoli.

E  Oxygen diffuses from the air into the deoxygenated (“used”) blood in the capillary beds, and carbon dioxide diffuses from that blood to the alveoli.

A  trachea.

B  pharynx.

C  bronchi.

D  alveoli. 

A  Humans need an internal transport system in order to quickly replace oxygen that is lost because of our high surface area of skin

B  Humans do not need as much oxygen as small organisms do, so we use inefficient transport systems like the circulatory system rather than diffusion.

C  Diffusion does not occur in organisms that have more than about 300 cells 

D  Diffusion is very slow over all but the shortest distances, so oxygen must be delivered to our cells to speed up the process

A  arteries.

B  ventricles.

C  be broken down into simple sugars

D  be stored temporarily as glycogen 

E  be converted into starch

A  the ability to maintain an absolutely constant internal body state

B  the ability to maintain the internal body state within a narrow range 

C  the constant state of the body

D  the varying of the body state within a narrow range

E  . the ability to produce heat and maintain an internal temperature.

A  hibernation

B  negative feedback

C  hypothermia

D  positive feedback 

E  the lowering of a set point
