What's carbon dioxide fixation?
|
THe transfer of carbon dioxide to organic compounds
|
|
What's NADPH?
|
an electron carrier that provides the high-engergy electrons needed to make carbon-hydrogen bonds in the third stage of photosynthesis. In an electron transport chain excited electrons combine with hydrogen ions as well as an electron acceptor called nadp+
|
|
Calvin Cycle
|
series of enzyme-assisted chemical reactions that produces a three-carbon sugar
|
|
aerobic
|
metabolic processes that require oxygen
|
|
anaerobic
|
metabolic process that doesn't require air.
|
|
glycosis
|
first stage of cellular respiration, glucose is broken down in the cytoplasm.
|
|
pyruvate
|
ion of a three carbon organic acid
|
|
NADH
|
hydrogen atoms that are transferred to an electron acceptor called nad+
|
|
Light absorbing________ are located in the membranes of __________.
|
pigament, thykaloids
|
|
The carrier protein that transports hyrdrogen ions across the thylakoid membranes and produce atp acts as both a(n) _________ and a(n)________
|
ion channel, enzyme
|
|
What are the the stages of photosynthesis?
|
First, engergy is captured from sunlight
Second energy is temporarily stored in arp and nadph third, organic compounds are made using atp nadph, and carbon dioxid |
|
During the areobic respiration, pyruvate is first converted to acetyl-CoA, which enters the________.
|
Krebs Cycle
|
|
Explain how ATP provices energy for cells.
|
When the bonds between the phosphate
groups of an ATP molecule are broken, energy is released. This energy can be used by the cell. |
|
Explain how artp is produced by electron transport chains during potosynthesis.
|
Excited electrons lose some energy as they
pass through electron transport chains. This energy is used to pump hydrogen ions, produced when water molecules are split, into the thylakoid. Special carrier proteins that function as both ion channels and as enzymes transport the now-concentrated hydrogen ions out of the thylakoid. As hydrogen ions pass through the ion channel part of the carrier protein, a phosphate group is added to a molecule of ADP, making ATP. |
|
Explain benefits and uses of lactic acid fermentation and alcoholic fermentation.
|
Fermentation enables cells to continue making
ATP, though in limited amounts, through glycolysis when oxygen is no longer available. Lactic acid fermentation is used in the production of foods such as yogurt and some cheeses. Alcoholic fermentation is used commercially in the preparation of bread, wine, and beer. |
|
What's the product of glycosis?
|
Two three carbon molecules of pyruvate
|
|
ATP and _______ are produced the second stage of photosynthesis
|
NADPH
|
|
ATP is made from ADP by adding a(n)______ group to a molecule of ADP.
|
phosphate
|
|
Photosynthetic organisms get energy from
|
light
|
|
Production fo ATP during photosynthesis requires?
|
1. Energy released from when hydrogen ions ove down their concetration gradient.
2. a carrier protein to catalyze the addition of a phosopate group to a molecule of ADP 3. engergy from electrons passing through electron transport chains |
|
In glycosis
|
four atp molecules are produced
|
|
carbon dioxide fixation in the calvin cyclerequires
|
atp and nadph.
|
|
during cellular respiration
|
the complete breakdwon of glucose yields only carbon dioxide
|
|
Glycolysis breaks down into two pyruvates
|
T
|
|
Glycolysis occurs during the second stage of cellular respiration
|
F
|
|
Acetyl-CoA
|
is formed from the breakdown of pyruvate and enters the Krebs cycle and combines with a four carbon compound.
|
|
Whats the equation for photosynthesis?
|
6CO2+6H^2O--->C6H12O6+6O2
|
