ACTUAL Questions and CORRECT
Answers
cellular metabolism - CORRECT ANSWER - all the chemical activities of a cell
metabolic pathways are - CORRECT ANSWER - a series of reactions in a particular order
catabolic pathways - CORRECT ANSWER - release energy by breaking down complex
molecules into simpler compounds
anabolic pathways - CORRECT ANSWER - consume energy to build complicated
molecules from simpler ones
Energy - CORRECT ANSWER - the capacity to do work or to move matter against
opposing forces
kinetic energy - CORRECT ANSWER - energy of motion or actually doing work
potential - CORRECT ANSWER - stored energy or not being used at the moment
chemical energy - CORRECT ANSWER - potential energy stored in molecules
Thermodynamics - CORRECT ANSWER - the study of energy transformations
the term system in thermodynamics means - CORRECT ANSWER - matter under study
,the term surroundings in thermodynamics means - CORRECT ANSWER - everything
outside the system
the term closed in thermodynamics means - CORRECT ANSWER - isolated from its
surroundings
the term open in thermodynamics means - CORRECT ANSWER - can be transferred
between systems and surroundings
organisms are - CORRECT ANSWER - open systems
First law of thermodynamics - CORRECT ANSWER - Energy can be transferred and
transformed, but it cannot be created or destroyed.
energy cant be - CORRECT ANSWER - created or destroyed only transformed
Entropy - CORRECT ANSWER - A measure of disorder or randomness.
the more random a collection of matter - CORRECT ANSWER - the greater its entropy
Free energy - CORRECT ANSWER - energy that is available to do work
Exergonic reactions are - CORRECT ANSWER - RELEASE energy and yield products
that contain less potential energy than their reactants. EXIT. FIRE. EXIT.
Endergonic reactions are - CORRECT ANSWER - ABSORB free energy from its
surroundings. Store energy. ENTER.
, ATP powers cellular work by - CORRECT ANSWER - coupling exergonic reactions to
endergonic reactions
G=H-TS - CORRECT ANSWER - T is temp in Kelvin
Mechanical work - CORRECT ANSWER - beating of cilia, contraction of muscle cells,
movement of chromosomes during cellular reproduction
Transport work - CORRECT ANSWER - the pumping of substances across membranes
against the direction of spontaneous movement
Chemical work - CORRECT ANSWER - the driving of endergonic reactions that would
not occur spontaneously
breathing and cellular respiration - CORRECT ANSWER - are closely related
ATP - CORRECT ANSWER - adenosine triphosphate
What is ATP? - CORRECT ANSWER - a close packing of nucleotide consisting of the
nitrogenenous base adenine, the sugar ribose, and a CHAIN OF THREE PHOSPHATE
GROUPS
Phosphate bonds in ATP are - CORRECT ANSWER - weak covalent bonds
phosphorylated - CORRECT ANSWER - the recipient of the phosphate group, a
transferring phosphate group to another molecule
ATP is a renewable resource that is regenerated by - CORRECT ANSWER - addition of a
phosphate group to adenosine diphosphate (ADP)
