Term
_____as implied by its name, is a cellular process that requires oxyygen and give off carbon dioxide.
Definition
cellular respiration
Term
Most often cellular respiration involves the complete breakdown of glucose to _____and_____.
Definition
carbon dioxide and water
Term
Glucose is a ____molecule and its breakdown products of CO2 and H2O are ____molecules.
Definition
high energy; low energy
Term
What is the respiration equation? go over moreeeew
Definition
c6h12o6 + 6o2---6c02 + 6 H2o + energy
Term
The buildup of ATP is an ____reaction, which requires energy.
Definition
endergonic
Term
HOw many ATPs make up a glucose?
Definition
36
Term
What are the four phases of cellular respiration without description?
Definition
glycolysis, preparatory reaction, citric acid cycle, and the electron transport chain
Term
Cellular respiration is a ____reaction because it releases energy. The buildup of ATP is a ____reaction because it stores energy.
Definition
exergonic; endergonic
Term
Because the breakdown of glucose yields the synthase of 36 or 38 ATP, what percentage of energy is preserved in glucose?
Definition
39 %
Term
NAD is sometimes called a ____.
Definition
redox coenzyme
Term
____is the breakdown of glucose in the cytoplasm into two molecules of pyruvate.
Definition
glycolysis
Term
Because glycolysis does not use oxygen, it is a ____reaction.
Definition
anaerobic
Term
In the _____reaction,pyruvate enters a mitochondrion and is oxidized to a 2 carbon acetyl group carried by CoA.
Definition
prep reaction
Term
The ______is a cyclical series of exidation reactions in the matrix of a mitochondrion that result in NADH and FaDH2.
Definition
citric acid cycle
Term
The _____is a series of carriers in the inner mitochondrial membrane that accept the electrons removed from glucose and pass them along from one carrier to the next until they are finally received by 02, which then combines with hydrogen ions and becomes water.
Definition
electron transport chain
Term
_____is a pivotal metabolite in cellular respiration.
Definition
pyruvate
Term
During ______, glucose is incompletely metabolized to lactate or to carbon dioxide and alchol, depending on the organism.
Definition
fermentation
Term
____is the breakdown of glucose to two pyruvate molecules.
Definition
glycolysis
Term
What is substrate level phosphorylation?
Definition
an enzyme passes a high energy phosphate to ADP and ATP results
Term
If oxygen is not available, _____occurs and pyruvate undergoes ____.
Definition
fermentation; reduction
Term
After glycolysis, CO2 and ATP are transported out of the mitochondria into the ____.
Definition
cytoplasm
Term
The _____connects glycolysis to the citric acid cycle.
Definition
prep reaction
Term
In the prep reaction, pyruvate is converted to a 2 carbon acetyl group attached to coenzyme A (CoA) and _____is given off.
Definition
carbon dioxide
Term
How many times does the prep reaction occur for each glucose molecule?
Definition
twice
Term
Where does the citric acid cycle occur?
Definition
in the matrix of the mitochondria
Term
What is the citric acid cycle sometimes called?
Definition
the crebs cycle
Term
citric avid cycle and electrons transport chain???
Definition
Term
Some forms of respiration are _____.
Definition
anaerobic
Term
What does anaerobic mean?
Definition
oxygen is not used
Term
What happens in fermentation?
Definition
pyruvate is reduced by NADH to either alcohol or carbon dioxide or to lactate
Term
____are unicellular fungi that carry on alcoholic fermentation when oxygen is absent.
Definition
yeast
Term
Animals including humans, certain bacteria, and fungi carry on ______in which NADH reduced pyruvate to lactate.
Definition
lactic acid fermentation
Term
Lactate is ____to cells.
Definition
toxic
