questions with verified answers
aerobic respiration Ans✓✓✓-requires oxygen
anaerobic respiration Ans✓✓✓-Does not use oxygen
At the end of the calvin cycle, energy is stored in what molecue? Ans✓✓✓-
C6H12O6
Calvin Cycle Ans✓✓✓-occurs in the stroma, uses ATP and carbon dioxide, and
produces sugars.
Cells use the energy stored in the ATP to do work. What happens to the ATP that
is used to power cellular reactions?
a) it does not change when the energy is released.
b) it is broken down to ADP and a phosphate.
c) it is lost as heat.
d) it is removed as a waste product. Ans✓✓✓-it is broken down to ADP and a
phosphate.
cellular respiration Ans✓✓✓-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)
chloroplasts Ans✓✓✓-are organelles that consist of a double membrane, similar
to that of mitochondria
, citric acid cycle or Krebs cycle Ans✓✓✓-happens in the inner space of the
mitochondria.
Does fermentation use the electron transport chain? Ans✓✓✓-No, the ETC
requires oxygen, and fermentation can occur in the absence of oxygen.
Electron transport chain Ans✓✓✓-electrons are passed to proteins on the inner
membrane of the mitochondria. they are passed from one protein to the next.
Energy used to power the light independent reaction is stored in which
molecules? Ans✓✓✓-ATP and NADPH
fermentation is an anaerobic process. This means that fermentation
______________. Ans✓✓✓-does not require oxygen.
Fermentation occurs in the ____________ of the cell. Ans✓✓✓-Cytoplasm
glycolysis Ans✓✓✓-happens in the cytosol of the cell. this is essential for the
breaking of a sugar molecule in half.
How, specifically, does oxygen enable aerobic cellular respiration? Ans✓✓✓-
Oxygen accepts high energy electrons from the electron transport chain in the
mitochondria, where most ATP is produced.
light dependent reaction Ans✓✓✓-occurs on the thylakoid membranes,
produces NADPH, and produces oxygen.
