ECPI BIO 111 Ch:4 Exam Questions
With 100% Verified Correct Answers.
Denaturation
Alteration of shape, if extreme enough then it alters function
Denaturation
Results in enzyme being unable to bind to substrate
Energy
Cannot be created or destroyed, but can be changed from one form to another
Common forms of energy
heat/thermal, light, sound, electrical energy, mechanical energy, chemical energy
Cellular respiration
process that transfers energy from molecules, and makes it available for cellular use
Final products of Cellular respiration
carbon dioxide, water, 40% ATP, 60% heat
Anaerobic reactions
do not require O2, and make little ATP
Aerobic reactions
Require O2, and make most of ATP
Oxidation
Releases energy from glucose and other molecules
Energy is held in ______, and released when bonds are broken
, Chemical bonds
What energy is transferred to ATP ?
40% is released as chemical energy; 60% is released as heat;maintains body temp
Each enzyme is specific to a particular
Substrate
The ability to recognize a substrate depends on
the shape of the active site of the enzyme
Cofactor
Non-protein substance that combines with enzyme to activate it; some help fold the active
site into proper conformation
Coenzyme
Organic molecule that acts as cofactor
Many metabolic processes require _____, which is stored in ATP
Chemical Energy
ATP consists of 3 portion:
Adenine, Ribose (a sugar), 3 phosphates in a chain
Cellular Respiration of glucose occurs in 3 interconnected catabolic reaction sequences
Glycolysis, citric acid cycle, Electron transport chain
Where does Glycolysis occur ?
cytosol
Where does the Citric acid cycle/ Krebs cycle occur?
mitochondrial matrix
