WGUC190 Intro to biology unit 4- Metabolism Exam Questions and
Answers with Verified Solutions | Latest 2026 Update
Q: photosynthesis
Answer:
Conversion of light energy from the sun into oxygen.
Q: cellular respiration
Answer:
the process of breaking down glucose into simpler molecules, releasing some of
the energy stored in the bonds, and converting it into adenosine triphosate (ATP)
Q: aerobic respiration
Answer:
requires oxygen
Q: anaerobic respiration
Answer:
Does not use oxygen
Q: Which types of molecules are useful for driving life processes in cells because
they contain a lot of energy stored in their chemical bonds?
Answer:
sugars and other organic molecules, and ATP.
Q: What is the ultimate source of almost all energy in the biosphere?
Answer:
sunlight
Q: what is ATP?
Answer:
ATP (adenosine triphosphate) is a molecule that contains high-energy phosphate
bonds, is present in all living cells, and provides energy for many cellular
activities.
What is the name of the organelle in a plant or algae cell that is mainly responsible
for photosynthesis? -
, Cholroplast
Q: chloroplasts
Answer:
are organelles that consist of a double membrane, similar to that of mitochondria
Q: light dependent reaction
Answer:
occurs on the thylakoid membranes, produces NADPH, and produces oxygen.
Q: Calvin Cycle
Answer:
occurs in the stroma, uses ATP and carbon dioxide, and produces sugars.
Q: Where does the electron end up at the end of the light dependent reaction?
Answer:
NADPH
Q: What is the energy lost as the electron is being passed from one molecule to
another in the light dependent reaction?
Answer:
ATP is formed.
Q: Energy used to power the light independent reaction is stored in which
molecules?
Answer:
ATP and NADPH
Q: At the end of the calvin cycle, energy is stored in what molecue?
Answer:
C6H12O6
Q: Which reaction supplies the majority of ATP for aerobic organisms
Answer:
Cellular respiration
Q: which organelle in eukaryotic cells is used for cellular respiration?
