6.1 Living Systems Require a Flow
... [Show More] of Energy
In a phrase, how do physicists define “energy”? Ability to do work
The physicist’s definition of energy is not ____________ __________ for use
in defining energy changes within a living cell.
Comprehensive enough
How would a cell biologist define “energy”? The ability to make specific changed occur
List 5 major sorts or categories of energy change within the cell. Fig 6.2. Biosynthesis- movement- concentration – electrical
potential- heat
Sometimes the cell pumps substances against diffusion forces that would
otherwise carry those substances the other way. What term/phrase would we
give to this pumping process? _____________ ___ _______________
Energy of concentration
On a cold day, which of the following processes do your cells depend on to
maintain an operating temperature of 37 degrees Celsius?
a. muscle contraction
b. shivering
c. respiration energy production
d. metabolic heat generation
e. all of the above
e
6.2 Laws of Energy Flow in the Living World
______ is freely convertible from one form to another but _______ can never
be created or destroyed in normal processes.
Energy
(That means that in nature, as energy freely changes from one form to another,
the total amount of energy stays constant.)
Thus, a lit match cannot continue to burn when the wood of the match stick is
consumed. This statement illustrates what general law of energy flow?
Law of conservation of matter & energy
Systems that convert energy from one form to another are not 100% efficient,
thus the amount of useful energy ___________.
decreases
This is because, in cars and in living things, energy conversion is inefficient,
with much energy being lost in the form of useless _______. Fig 6.4
Heat energy
So, when your car engine burns the octane in gasoline, in what form does at
least 50% of the energy of the octane end up?
Heat energy
In a crowded, unventilated room, what causes the temperature to rise? glucose
What form of energy do producers use when they set about to generate
chemical energy—the energy of C―H and C―O―H bonds?
solar
Thus, a producer organism is called a “producer” because it converts solar
energy to usable ______ _______. Fig 6.5 “Energy In”
