UPDATED Exam Questions and CORRECT
Answers
cellular respiration - CORRECT ANSWER - use of oxygen to release energy from
nutrients
cellular respiration - CORRECT ANSWER - energy that is stored in the food that we eat is
converted to the body's energy molecule ATP
ATP - CORRECT ANSWER - small organic molecule with three phosphate groups
attached that acts as the direct source of energy for almost all cellular activities
ATP - CORRECT ANSWER - a relatively unstable molecule
ATP - CORRECT ANSWER - never used for long-term storage of energy in the cell
ATP - CORRECT ANSWER - used for direct and rapid transfers of energy
inputs into the cellular respiration pathway - CORRECT ANSWER - organic molecules
and oxygen
outputs of cellular respiration - CORRECT ANSWER - carbon dioxide, water, and energy
in the form of ATP
aerobic - CORRECT ANSWER - a process that requires oxygen
NADH - CORRECT ANSWER - an electron carrier molecule produced in glycolysis and
the Krebs cycle
, FADH2 - CORRECT ANSWER - one of the electron carrier molecules produced in the
Krebs cycle of aerobic cellular respiration
NADH and FADH2 - CORRECT ANSWER - molecules that provide the transport of
high-energy electrons from one step of cellular respiration to another
organelle used for cellular respiration - CORRECT ANSWER - mitochondria
glycolysis - CORRECT ANSWER - step one of cellular respiration
glycolysis - CORRECT ANSWER - the breakdown of glucose into pyruvate
glycolysis - CORRECT ANSWER - occurs in the cytoplasm and produces small amounts
of the energy molecule ATP and the electron carrier NADH
glycolysis - CORRECT ANSWER - essentially the breaking of a sugar molecule in half
glucose - CORRECT ANSWER - the most common sugar used in glycolysis
glucose - CORRECT ANSWER - a six carbon sugar
pyruvate - CORRECT ANSWER - a three carbon molecule that is the output of glycolysis
glycolysis - CORRECT ANSWER - breaks down glucose with or without oxygen present
fermentation - CORRECT ANSWER - breaks down molecules and stores energy as ATP
