NCHS FINAL EXAM REVIEW 2025 ACTUAL QUESTIONS AND ANSWERS
Steps of photosynthesis - CORRECT ANSWER✅✅1. Light Dependent Reaction
2. Light Independent Reaction
Steps of Cellular Respiration - CORRECT ANSWER✅✅1. Glycolysis
2. Kreb's Cycle
3. Electron Transport Chain
Photosynthesis Equation - CORRECT ANSWER✅✅6CO2 + 6H2O + light ------> C6H12O6 + 6O2
Cellular Respiration Equation - CORRECT ANSWER✅✅C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP
Light Dependent Reaction - CORRECT ANSWER✅✅reactions of photosynthesis that use energy from
light to produce ATP and NADPH. Water is used/split and oxygen is a byproduct.
Light Independent Reaction - CORRECT ANSWER✅✅a reaction of photosynthesis that uses ATP,
NADPH, and carbon dioxide to make high-energy sugars (glucose).
Glycolysis - CORRECT ANSWER✅✅first step in cellular respiration, in which a molecule of glucose is
broken into two molecules of pyruvate
Kreb's Cycle - CORRECT ANSWER✅✅second stage of cellular respiration, in which pyruvate is broken
down into carbon dioxide
electron transport chain - CORRECT ANSWER✅✅a series of proteins in which the high-energy electrons
from the electron carriers, NADH & FADH2, are used to convert ADP into ATP. (~36 total ATP made)
Relationship between Photosynthesis and Cellular Respiration - CORRECT ANSWER✅✅The products of
one are the reactants of another.
, Chloroplast - CORRECT ANSWER✅✅Site of photosynthesis
Mitochondria - CORRECT ANSWER✅✅Site of Cellular Respiration
ATP - CORRECT ANSWER✅✅(adenosine triphosphate) main energy source that cells use for most of
their work
energy _____ through an ecosystem. - CORRECT ANSWER✅✅flows
matter _______ through an ecosystem - CORRECT ANSWER✅✅cycles
Producers - CORRECT ANSWER✅✅Organisms with the most energy available to them because they
produce their own food.
Consumers - CORRECT ANSWER✅✅Organisms that consume other organisms and have the less energy
available to them.
Decomposers - CORRECT ANSWER✅✅Organisms that break down dead organisms into usable matter
for the producers.
10% - CORRECT ANSWER✅✅Amount of energy that is transferred from one organism to the next.
90% - CORRECT ANSWER✅✅Amount of energy that is lost as heat to the environment.
Food Web - CORRECT ANSWER✅✅a system of interlocking and interdependent food chains.
Food Chain - CORRECT ANSWER✅✅A series of steps in which organisms transfer energy by eating and
being eaten
