Biology The Core Exam 2 complete
study set with Questions and correct
simplified Answers
Enzymes - correct answer- ✅a protein that speeds up chemical reactions without being
changed itself
Metabolic Pathway - correct answer- ✅A. Substrate (Enzyme 1) B. Intermediate (Enzyme 2) C.
Product
Active Site - correct answer- ✅the substrate binds to an enzyme at a particular place
Activation Energy - correct answer- ✅is the amount of energy required for a chemical reaction
to proceed
Competitive Inhibitors - correct answer- ✅blocking the active site
Non-Competitive - correct answer- ✅Changing the shape of the active site
Potential Energy - correct answer- ✅stored energy, all foods
Kinetic Energy - correct answer- ✅energy in motion, cheetah chasing the wildebeest
1st Law of Thermodynamics - correct answer- ✅energy cannot be created or destroyed, only
transformed
2nd Law of Thermodynamics - correct answer- ✅energy transfer always results in a greater
amount of disorder (some energy is "lost" as heat)
Entropy - correct answer- ✅from order to disorder ex. Dr. Plasters dining room from Sunday to
Saturday
Exergonic - correct answer- ✅energy going out, disorderly
Endergonic - correct answer- ✅energy going in, orderly, also known as coupled reaction
Chemical Reaction is either ___________ or ____________. - correct answer- ✅exergonic
and endergonic
Moving a substance from low to high concentration with the use of energy - correct answer-
✅Active Transport
Movement of molecules from an area of high to low concentration - correct answer- ✅Simple
Diffusion
Substance transported with the help of a protein, moves high to low concentration - correct
answer- ✅Facilitated Diffusion
The diffusion of water from high to low concentration - correct answer- ✅Osmosis
Decomposers - correct answer- ✅consumers that obtain nutrients from dead organisms and
organic wastes
Cellular Respiration Equation - correct answer- ✅C6H12O6 (glucose) + 6O2 (oxygen) = 6CO2
(carbon dioxide) + 6H20 (water)
Photosynthesis Equation - correct answer- ✅6CO2 (carbon dioxide) + 6H20 (water) =
C6H12O6 (glucose) + 6O2 (oxygen)
From where does the initial energy for photosynthesis come from? - correct answer- ✅the sun
Aerobic Respiration requires what? - correct answer- ✅Oxygen
