A-B->A+B - CORRECT ANSWER: Lyases
A-B->B-A - CORRECT ANSWER: Isomerases
A-B+H2O ->A-OH+B-H - CORRECT ANSWER: Hydrolases
A+B->A-B - CORRECT ANSWER: Ligases
An organism that derives its energy by removing electrons from elemental sulfur would
be classified as a ____________ - CORRECT ANSWER: Lithotroph
An organism that obtains its energy (derives ATP) from photons of light is called a
__________________ - CORRECT ANSWER: phototrophic microorganism
Describe the energy transfer process relative to both ADP and ATP - CORRECT
ANSWER: ATP has the energy (phosphate group) to donate, and ADP can accept
energy in the form of a phosphate group. Thus, ATP can be dephosphorylated (ATP-----
> ADP + Pi), while ADP can be dephosphorylated into ATP (ADP + Pi -----> ATP)
Describe the relationship between chloroplasts and chlorophyll - CORRECT ANSWER:
both are associated with photosynthesis. Chloroplasts are the double membrane
enclosed organelles that contain the photosynthetic pigment chlorophyll
For the catabolism of proteins and lipids, which enzymes are used? - CORRECT
ANSWER: lipases and proteases
, How many turns or repetitions of the Calvin cycle are required to generate one molecule
of glucose? - CORRECT ANSWER: six
In the absence of glucose, what cannot be used as alternative energy source? -
CORRECT ANSWER: nucleic acids
MEMORIZE THE NUMBERS - CORRECT ANSWER: 6, 18, 12, 12, 18, 12
The catabolism of a single molecule of glucose goes through what three transitions -
CORRECT ANSWER: The breakdown of glucose goes through 1. glycolysis 2.
fermentation or respiration and then 3. electron transport chain ETC
the process of carbon fixation begins with reactants: - CORRECT ANSWER: ATP, CO2,
NADPH, H2O
The reactants of the chemical equation are to the _____ of the arrow - CORRECT
ANSWER: left
The term for metal ions that assist enzymes during the catalysis reaction - CORRECT
ANSWER: cofactors
This phosphorylation process occurs in the mitochondria of chemotropic eukaryotes -
CORRECT ANSWER: oxidative phosphorylation
True or false, dark reactions can take place in the presence or absence of light -
CORRECT ANSWER: True, the term dark reactions (also known as Calvin cycle) simple
denotes the second stage of photosynthesis - does not actually require darkness
True or false: enzymes slow down chemical reactions to conserve energy - CORRECT
ANSWER: false, they speed up (catalyze) chemical reactions
