Terms in this set (28)
The amount of energy needed to raise the temperature of 1 gram of water 1 degree Celsius
(Capital C) Used on food lables, and is a kilocalorie, or 1,000 calories
Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
Cell Respiration reactants
glucose and oxygen
Cell Respiration products
Carbon dioxide, water, and energy (ATP)
Organelle in eukaryotes where cellular respiration occurs
Three main phases of cell respiration
Glycolysis, the Krebs cycle, and the electron transport chain
Process that requires oxygen
The Krebs cycle and the ETC
Which process(es) in cellular respiration are aerobic?
Process that does not require oxygen
Which process(es) in cellular respiration are anaerobic?
Location where glycolysis occurs
In the mitochondria
Where do the Krebs cycle and the electron transport chain occur?
First set of reactions in cellular respiration in which a molecule of glucose is broken down into two molecules of pyruvic acid and NADH and 2 ATP molecules are formed
NAD+ (nicotinamide adenine dinucleotide)
Electron carrier involved in glycolysis
It becomes NADH
What happens to NAD when it accepts a pair of high-energy electrons?
Is the glycolysis process fast or slow? Is the time it takes an advantage or disadvantage?
Second stage of cellular respiration in which pyruvic acid is broken down releasing carbon dioxide, as the hydrogens are extracted to form NADH and FADH2 . 2 ATP are also produced
The innermost compartment of the mitochindrion and the site of the Krebs cycle reactions
Allows gylcolysis continue under anaerobic conditions
Is fermentation aerobic or anaerobic?
Pyruvic acid and NADH
What are the reactants of fermentation?
Products of alcoholic fermentation
Ethyl alcohol, carbon dioxide, and NAD+
Products of lactic acid fermentation
lactic acid and NAD+
Final electron acceptor in the ETC
releases carbon dioxide into the atmosphere
removes carbon dioxide from the atmosphere
Electron Transport Chain
Uses the high-energy electrons from NADH and FADH2 to produce ATP
