NUR 3125 UCF Exam 1 Questions With Complete Solutions1st phase of cellular catabolism Correct Answers Digestion.
Large molecules are broken down into smaller subunits: proteins
into amino acids, polysaccharides into simple sugars (i.e.,
monosaccharides), and fats into fatty acids and glycerol. These
processes occur outside the cell and are activated by secreted
enzymes.
2nd phase of cellular catabolism Correct Answers Glycolysis
and oxidation. The most important part of phase 2 is glycolysis,
the splitting of glucose. Glycolysis produces two molecules of
ATP per glucose molecule through oxidation, or the removal
and transfer of a pair of electrons. The total process is called
oxidative cellular metabolism and involves 10 biochemical
reactions
3rd phase of cellular catabolism Correct Answers Citric acid
cycle (Krebs cycle, tricarboxylic acid cycle). Most of the ATP is
generated during this final phase, which begins with 18the citric
acid cycle and ends with oxidative phosphorylation. About two-
thirds of the total oxidation of carbon compounds in most cells
is accomplished during this phase. The major end products are
CO2 and two dinucleotides—reduced nicotinamide adenine
dinucleotide (NADH) and the reduced form of flavin adenine
dinucleotide (FADH2)—both of which transfer their electrons
into the electron-transport chain
5 carbon sugar Correct Answers deoxyribose
, Active Transport Correct Answers Movement of solute
AGAINST its concentration gradient. Solutes are actively
pumped across semi permeable membranes from an area of
LOWER concentration to an area of HIGHER concentration.
Requires energy from ATP.
aerobic glycolysis Correct Answers The breakdown of
glycogen in the presence of oxygen to produce energy, carbon
dioxide, water and heat. Lots of ATP are formed
anaerobic glycolysis Correct Answers the overall process
where pyruvic acid generated during glycolysis is converted to
lactic acid and a small amount of ATP
