Metabolism and energy
1.
The conversion of glucose to carbon dioxide and water is an example of:
an esterification reaction
an anabolic reaction
a catabolic reaction.
a condensation reaction
2.
Which of the following is
not
a feature of collision theory?
at high temperatures molecules have more energy than at low temperatures
the rate of chemical reactions increases with increasing temperatures
the more molecules present, the faster the reaction
the reaction is faster in dilute solute solutions than in concentrated
3.
Catalysts:
provide an alternative reaction pathway
slow down chemical reactions
increase the activation energy
are used up in reactions
4.
In an endergonic reaction:
energy is absorbed from the surroundings
bonds being formed are the same strength as bonds being broken
energy is released to the surroundings
bonds being formed are stronger than bonds being broken
5.
In an exergonic reaction:
energy is released to the surroundings
bonds being formed are stronger than bonds being broken
energy is absorbed from the surroundings
bonds being formed are the same strength as bonds being broken
6.
Examples of anabolic reactions include:
the breakdown of carbohydrates
hydrolysis reactions
the build up of proteins
the breakdown of lipids
