QUESTION 4
The phosphate components of a membrane phospholipid bilayer are:
Polar and are oriented toward the water on either side of the membrane
Attracted to the lipid components of the membrane by hydrophobic interactions
Covalently linked to ATP
Spatially located in the membrane interior, while the fatty acids directly interface with the water on either side of the membrane
2.5 points
QUESTION 5
The second law of thermodynamics states that any real process can occur only if randomness in the universe increases. How then do we explain the observation that the collections of matter we call biological organisms are able to increase and maintain their internal order?
Matter assembled into biological organisms is a special case. It operates outside the boundaries described by thermodynamic laws.
Biological organisms actually are not very organized.
Enzymes alter the thermodynamics of processes.
The enthalpy of fuel metabolism drives internally organizing processes, and this internal reduction of disorder is exceeded by the increase in disorder in the organism
