(C) Two reactions that occur in the same organelle
(D) Reactions that occur during sexual reproduction
(E) Two reactions, where the product of the first reaction is the
reactant of the second reaction.
Answer: (E) Two reactions, where the product of the first reaction is
the reactant of the second reaction
◉ force acting on an object that causes it to move.
Answer: Work
◉ Chemical energy is located in what 3 things?.
Answer: sugar, glycogen, and fat
◉ energy that is in molecules and released by chemical reactions.
Answer: Chemical energy
,◉ Cells use ATP for what?.
Answer: accept and transfer energy from one chemical reaction to
the next
◉ Examples of potential energy.
Answer: rock at top of hill
electrical charge in batter
◉ type of energy that is stored.
Answer: Potential energy
◉ Examples (4) of kinetic energy.
Answer: light, heat, electricity, movement of objects
◉ type of energy using movement.
Answer: Kinetic energy
◉ Laws of thermodynamics ( first law).
Answer: Energy can not be created nor destroyed but can change
form
,◉ Another name for the 1st law of thermodynamics.
Answer: law of conservation energy
◉ Law of thermodynamics ( second law).
Answer: decreases when energy is converted from one form to
another
◉ The measure of disorder or more precisely unpredictability.
Answer: Entropy
◉ System moves towards or away from maximum entropy?.
Answer: towards (puddle)
◉ Chemical reactions ____________ reactants into products.
Answer: convert
◉ energy conversions = loss OR gain of useful energy.
Answer: loss

overcome repulsion and react?.
Answer: fast
◉ reactions that release energy
reactants contain more energy than products.
Answer: Exergonic reactions
◉ Increasing the temp increases or decreases kinetic energy?.
Answer: increases
◉ example of exergonic reaction.
Answer: cellular respiration/burning glucose
