1
New cards
Cellular Respiration
The process of breaking down complex organic compounds into simpler molecules and producing ATP
2
New cards
Glycolysis
The breakdown of glucose into 2 pyruvic acid molecules
3
New cards
Anaerobic pathways
A process of cellular respiration that does not need oxygen
4
New cards
pyruvate
The three-carbon compound that is produced during glycolysis and needed for both the aerobic and anaerobic pathways of cellular respiration
5
New cards
NADH
The reduced form of NAD(+) an electron-carrying molecule that functions in cellular respiration
6
New cards
aerobic respiration
the process in which pyruvic acid is broken down and NADH is used to make a large amount of ATP the part of respiration that is carried out in the presence of oxygen
7
New cards
glycolysis
The first step in cellular respiration
8
New cards
fermentation
the breakdown of carbohydrates by enzymes, bacteria, yeasts, or mold in the absence of oxygen (not anerobic)
9
New cards
lactic acid fermentation
the chemical breakdown of carbohydrates that produces lactic acid as the main end product
10
New cards
alcoholic fermentation
the anaerobic process by which yeasts and other microorganisms break down sugars to form carbon dioxide and ethanol
11
New cards
Chemiosmosis
The process of using hydrogen ions and ATP synthase to produce ATP
12
New cards
Krebs cycle
A series of biochemical reactions that convert pyruvic acid into carbon dioxide and 2 ATP
13
New cards
Heterotroph
An organism that needs to eat or consume food to survive
14
New cards
ATP synthase
The enzyme that make ATP from ADP and inorganic phosphate.
15
New cards
mitochondrial matrix
the fluid that is inside the inner membrane of a mitochondrion
16
New cards
Cristae
folds of the inner mitochondrial membrane
17
New cards
inner mitochondrial membrane
location of electron transport chain
18
New cards
outer mitochondrial membrane
the smooth membrane covering the outside of a mitochondrion
19
New cards
intermembrane space
the space between the outer and inner membrane of mitochondria
20
New cards
Ethanol
an alcohol that is formed as a product of fermentation in yeast
21
New cards
lactic acid
a product of fermentation in many types of cells, including human muscle cells
