cellular respiration
the process of releasing energy from glucose
mitochondria
this cell organelle carries out aerobic cellular respiration
CO2
chemical formula for carbon dioxide
H2O
chemical formula for water
C6H12O6
chemical formula for glucose
aerobic respiration
glucose is broken down when it combines with oxygen
anaerobic respiration
glucose is broken down without oxygen
anaerobic respiration
Lactic acid fermentation and alcoholic fermentation are both examples of what?
lactic acid fermentation
process where ATP is produced when muscles run out of oxygen during vigorous activity
alcohol fermentation
process that causes bread dough to rise. (Yeast ferments, giving off carbon dioxide bubbles that form air spaces in slices of bread, alcohol evaporates when bread is baked)
carbon dioxide and water
What are the products in cellular respiration (words)?
glucose and oxygen
What are the reactants in cellular respiration(words)?
6CO2 + 6H2O
products in cellular respiration (formulas)
C6H12O6 + 6O2
reactants in cellular respiration (formulas)
C6H12O6 + 6O2 yields 6CO2 + 6H2O
formula for cellular respiration
Adenosine Tri-Phosphate
ATP is the abreviation for this
ATP
Universal energy "currency" used by all cells.
ATP
Product when energy is added to ADP + P
ADP + P
products when energy is removed from ATP
Energy
The ability to do work
Work
moving a mass for some distance in some amount of time
Phosphate
Substance added to ADP to form ATP
Electron Carrier
Molecule that can transport energized electrons within the cell
NAD+
"Discharged" form of NADH (electron missing)
NADH
"Charged" form of NAD+ (electron added)
NAD+
when a hydrogen atom and an electron are removed from NADH
NADH
when a hyrdrogen atom and an electron are added to NAD+
Glycolysis
"Breaking sugar"
Glycolysis
process that results in 2 molecules of pyruvic acid, 2 ATPs, and 2 NADH
Glycolysis
First step in cellular respiration, takes place in the cytoplasm
Citric Acid Cycle
second step in aerobic cellular respiration, takes place in the matrix of the mitochondria.
Citric Acid Cycle
process of cellular respiration that produces CO2, NADH, and ATP from pyruvate
Oxidative Phosphorylation
third step in aerobic cellular respiration, takes place on the inner membrane of mitochondria
Oxidative Phosphorylation
process of cellular respiration that takes in oxygen, produces water, NAD+ and 34 ATPs
Krebs Cycle
Another name for the citric acid cycle
pyruvic acid
3 carbon molecule, two of these are produced in glycolysis
pyruvate
another name for pyruvic acid
mitochondrial matrix
where the citric acid cycle takes place
cytoplasm
where glycolysis takes place
inner membrane of mitochondria
where oxidative phosphorylation takes place.
electron transport chain
another name for oxidative phosphorylation
aerobic
any process that requires air (oxygen)
anaerobic
any process that does not require air (oxygen)
anaerobic respiration
breakdown of glucose to make ATP without oxygen
Fermentation
another term for anaerobic respiration
lactic acid
waste product produced in human cells when pyruvate is broken down anaerobically
alcohol + CO2
waste products produced in yeast cells when pyruvate is broken down anaerobically
