1. Suppose you plant a seed and observe that a tree of large mass grows from it. The tree achieves a final

mass that changes very little for years afterward. Which of the following is true about the tree? (1 point)
Both anabolic and catabolic reactions took place in the seed and tree when it was young and
growing, but then all reactions stopped when the tree reached a stable mass.
Both anabolic and catabolic reactions took place in the seed and tree when it was young and
growing, and both continue now even though the tree reached a stable mass.
Only anabolic reactions took place in the seed and tree when it was young and growing, and
only catabolic reactions continue now that the tree reached a stable mass.
Only catabolic reactions took place in the seed and tree when it was young and growing, and
only anabolic reactions continue now that the tree reached a stable mass.
2. What is the difference between an exergonic reaction and an endergonic reaction? (1 point)
An exergonic reaction results in a decrease in mass and an endergonic reaction results in an
increase in mass.
An exergonic reaction results in an increase in mass and an endergonic reaction results in a
decrease in mass.
An exergonic reaction involves release of energy and an endergonic reaction involves
absorption of energy.
An exergonic reaction involves an absorption of energy and an endergonic reaction involves
release of energy.

element identities of atoms in reactants
total number of electrons in reactants
chemical bonds between atoms in reactants
