I’m stuck on a Biology question and need an explanation.
1.
The Calvin Cycle of photosynthesis takes place in the:
thylakoids
stroma
stomata
cytoplasm
mitochondria
2.
What are the products of the light reactions?
glucose, ATP, and NADPH
CO2, H2O, and glucose
glucose, ATP, and O2
O2, NADP+, and ATP
O2, NADPH, and ATP
3.
The pigment chlorophyll most reflects which wavelength (color) of light?
violet
blue
red
green
orange
4.
Which molecule is split in order to replace the electron that is lost from chlorophyll in Photosystem 2 during the light reactions?
CO2
H2O
ATP
O2
C6H12O6
5.
Which of the following statements about photosynthesis is incorrect?
for every six molecules of CO2 that enter the Calvin Cycle, one molecule of glucose is created
glucose is created during the Calvin Cycle
99.9% of living things on Earth depend on photosynthesis either directly or indirectly for food
even if a plant was in complete darkness for an extended period of time, the Calvin Cycle could continue to produce glucose
light provides the energy boost to excite electrons during the first stage of photosynthesis
6.
During photosynthesis:
water is reduced.
glucose loses electrons
carbon dioxide loses electrons
water loses electrons.
carbon dioxide is oxidized
7.
What is the name of the specialized cells that allow the stomata to open and close (and hence conserve water in the plant)?
guard cells
magic cells
transport proteins
mesophyll
8.
What is the name of the electron carrier that is used during photosynthesis?
NADPH
Photosystem 1
C3P
RuBP
9.
Photosynthesis is an exergonic reaction.
True
False
10.
What does “fixing” carbon mean?
loading carbon into an electron carrier
taking carbon from the atmosphere and incorporating it into organic compounds
changing carbon found in sugars into ATP
changing the structure of the carbon atom so it bonds more effectively
nothing – if it ain’t broke, don’t fix it
