What are the byproducts of light reactions used for in dark reactions? ---------
CORRECT ANSWER-----------------The ATP and NADPH produced via light reactions
are used in dark reactions to convert carbon dioxide and water into organic
carbon compounds as well as useful carbohydrates (a process called carbon
fixation)
What is the chemical reaction for the Calvin cycle? ---------CORRECT ANSWER-------
----------6 CO2 + 18 ATP + 12 NADPH + 12 H2O --> C6H12O6 + 18 ADP + 12 NADP+
What determines the specificity of an enzyme? ---------CORRECT ANSWER------------
-----The specificity of an enzyme is heavily influenced by its active site - a unique
chemical structure bound only by select target molecules. The structure is
influenced by the amino acid composition of the protein as this in turn influences
the fold, shape, and 'appearance' of the enzyme. The active site (and its target
protein) can be thought of as a lock-and-key relationship. The active site provides
specificity (like a lock) that only specific target proteins can bind - much like how
only a specific key will fit into, unlock, and 'activate' a lock
Do catabolic reactions release or consume energy? ---------CORRECT ANSWER-------
----------Release
,Do anabolic pathways release or consume energy? ---------CORRECT ANSWER-------
----------Consume
Do catabolic pathways rely on oxidized cofactors (like NAD+) to oxidize
intermediates, or do they rely on reduced cofactors (like NADPH) to reduce
intermediates? ---------CORRECT ANSWER-----------------They rely on oxidized
cofactors (like NAD+) to oxidize intermediates
Do anabolic pathways rely on oxidized cofactors (like NAD+) to oxidize
intermediates, or do they rely on reduced cofactors (like NADPH) to reduce
intermediates? ---------CORRECT ANSWER-----------------They rely on reduced
cofactors (like NADPH) to reduce intermediates
Is cellular respiration catabolic or anabolic? ---------CORRECT ANSWER-----------------
Catabolic
Is lipid biosynthesis catabolic or anabolic? ---------CORRECT ANSWER-----------------
Anabolic
, Cofactors ---------CORRECT ANSWER------------------Metal ions that activate or
enhance enzyme activity (like Ca2+ or Zn2+)
-Regulate enzymes
What is cellular metabolism? ---------CORRECT ANSWER-----------------Metabolism is
a controlled set of biochemical reactions that occur in living organisms in order to
maintain life
What is the primary function of enzymes, and how are they regulated? ---------
CORRECT ANSWER-----------------Enzymes speed up chemical reactions. Most
notably, the enzyme is not consumed during the reaction and can be used
repeatedly by the cell. Enzymes can also be regulated by a cofactor such that in
the absence of the proper cofactor, enzymes are inactive while in its presence
enzymes are active.
What is the difference between catabolism and anabolism? ---------CORRECT
ANSWER-----------------Catabolism is the process of breaking down larger molecules
into useful energy sources whereas anabolism is the building up or biosynthesis
od macromolecules from smaller molecular units into larger complexes, most
often associated with cellular growth and repair
ATP has the energy to ______, while ADP has the capacity to ______ energy. ------
---CORRECT ANSWER-----------------Donate, accept
