BIOL 1050 EXAM 2 QUESTIONS WITH
CORRECT ANSWERS
Metabolism - Correct Answers -combination of all the chemical reactions within an
organism
exergonic reaction - Correct Answers -A chemical reaction that releases energy
endergonic reaction - Correct Answers -Reaction that absorbs energy from its
surroundings.
anabolic reactions - Correct Answers -build up large chemicals and require energy
catabolic reactions - Correct Answers -break down large chemicals and release energy
ATP - Correct Answers -(adenosine triphosphate) main energy source that cells use for
most of their work
How ATP works - Correct Answers -transferring a phosphate
to other molecules, bond between 2nd and 3rd phosphate breaks
Ezymes - Correct Answers -protiens that speed up chemical reactions
enzyme active site Importance - Correct Answers -bind through active sites, reposition
the substrates so less energy is needed
non-competitive inhibition - Correct Answers -a molecule binds a separate site on the
enzyme, changing it's shape
cell respiration purpose - Correct Answers -to convert glucose molecules into usable
ATP energy
where is at occurs - Correct Answers -glycolysis = cytoplasm
krebs cycle = matrix
ETC = membrane
Part of the mitochondria - Correct Answers -- outer membrane
-inner membrane
-cristane
