34 terms
Terms | Definitions |
|---|---|
 calorie | the amount of energy needed to raise the temperature of 1 gram of water 1 degree celcius |
| glycolysis | the process in which a glucose molecule is split in half |
| pyruvic acid, a 3 carbon compound | what is the product of glycolysis |
| cellular respiration | process that releases energy by breaking down glucose and other food molecules in the presence of oxygen |
| NAD+ | (nicotinamide adenine dinucleotide) an electron carrier molecule that helps to pass energy from glucose to other pathways in the cell |
| fermentation | process by which cells release energy in the absence of oxygen |
| anaerobic | process that doesn't require oxygen |
| aerobic | process that requires energy |
| kreb cycle | 2nd stage of cellular respiration in which pyruvic acid is broken down into carbon dioxide in a series of energy extracting reactions |
| electron transport chain(ETC) | a series of proteins in which the high energy electrons from the kreb cycle are used to convert ADP to ATP |
| mitochondria | where the final stage of cellular respiration takes place |
| chloroplasts | where does photosynthesis takes place |
| to make ATP | what is the purpose of cellular respiration |
| make glucose | what is the purpose of photosynthesis |
| glycolysis | first step in cellular respiration |
| glycolysis | the process of turning 1 glucose into 2 pyretic acid |
| cytoplasm, outside of the mitochondria | where does glycolysis take place |
| NAD+ | what is the electron acceptor in glycolysis |
| NADH | what does NAD+ turn into in glycolysis |
| break down food into ATP | what is the purpose of cellular respiration |
| 6O2+C6H12O6----->6H2O+6CO2 | what is the equation for cellular respiration |
| 2 pyruvic acid | what does glycolysis turn 1 glucose into |
| energy investment phase | phase in glycolysis that involves putting in 2 ATP to get the reaction started |
| energy yielding phase | phase in glycolysis where 2 PGAL are turned into 2 pyruvic acid, another 3 carbon molecule and releases 4ATP with net gain of 2 ATP and 2 NAD+ turned into 2 NADH |
| Hans Kreb | who is the kreb cycle named after |
| matrix of mitochondria | where does the kreb cycle take place |
| citric acid cycle | what is another name for the krebs cycle |
| make more electron carriers to make ATP in the ETC | what is the purose of the krebs cycle |
| 4co2, 6 NADH, 2 FADH2 and 2ATP | what does krebs cycle result in |
| alcohol and lactic acid | what are the 2 main types of fermentation |
| oxygen | what is the last electron acceptor of the ETC |
| muscle | where does lactic acid fermentation take place during rapid exercise? |
| glycolysis | if oxygen is present, what do kreb cycle and electron transport chain follow |
| citric acid is the first product | why is the kreb cycle known as citric acid cycle? |
