BIOL 1104 Final Exam Actual
Questions With Verified Answers
\.Energy not converted to useful energy is given off as.. - Answer- heat
\.1st law of thermodynamics - Answer- The principle of conservation of energy. Energy can
be transferred and transformed, but it cannot be created or destroyed.
\.during photosynthesis, plants convert light into chemical energy, this is - Answer- an
example of the first law of thermodynamics
\.ultimate source of energy for most of life on earth? - Answer- the sun, solar energy
\.energy is - Answer- the capacity to do work
\.exergonic reaction - Answer- An energy-releasing chemical reaction in which the reactants
contain more potential energy than the products. The reaction releases an amount of energy
equal to the difference in potential energy between the reactants and the products.
\.sodium hydroxide being added to water, and the water getting hot is an example of.. - Answer-
exergonic reaction
\.photosynthesis is considered an endergonic reaction in an isolated plant because... - Answer-
low energy reactants are converted into high energy products.
, \.coupled reaction - Answer- two reactions that involve one providing energy for the other
\.most common energy carrier molecule of living organisms is... - Answer- ATP
\.a high energy bond in an ATP molecule is located between - Answer- 2 phosphate groups
\.when a muscle cell demands energy to perform its work of contraction, what happens to ATP -
Answer- ATP is broken down
\.most reactions in the body occur too slowly to sustain life, this is because... - Answer- many
reactions require large inputs of activation energy
\.high temeperature... - Answer- lowers the activation energy in a biochemical reaction
\.the reactants in enzyme catalyzed reactions is the... - Answer- substrate
\.allosteric activation - Answer- Binding of a molecule to a site other than the active site that
positively affects the binding of a substrate to the enzyme's active site.
\.competitive enzyme - Answer- binds to an active site and blocks substrate from binding
\.non-competitive enzyme - Answer- binds to other site than active site
\.thylakoid - Answer- A flattened membrane sac inside the chloroplast, used to convert light
energy into chemical energy.
