| Question | Answer |
|---|---|
| anabolic reaction | building a reaction requires energy endergonic |
| catabolic reaction | breakdown of a reaction releases energy exergonic |
| enzymes | control rate of metabolic reactions |
| aerobic | requires oxygen |
| anaerobic | no oxygen required |
| glycolysis | breakdown of sugar anaerobic |
| glycolytic process | 10 steps 2 atp required 4 atp produced |
| conversion of pyruvate to acetyl coa, citric acid cycle, and Electron transport chain | aerobic reaction, 36 atp produced |
| electron transport chain | located in the inner mitochondrial membrane, redox reactions, donate and accept electrons. |
| citric acid cycle | occurs in mitochondrial matrix, 2 atp from glucose |
| in catabolic pathways | monosaccharides are used to generate atp from anabolic reactions |
| in anabolic pathways | monosaccharides can be stored as glycogen, and converted to fat |
| anaerobic glycolysis | ,pyruvate can be converted to ethanol, pyruvate turns into lactic acid and can ferment into lactic acid |
| dna | deoxyribose nucleic acid, contains; pentose sugar, nitrogen base, and phosphate group. |
| rna | single strand, whas a ribose, nitrogen base, and phosphate. backbone made of sugars alternating with phosphate group. |
| mrna | messenger rna, carries the code for the protein to be synthesized from the nucleus to synthesis in the cytoplasm, by the ribosome |
| trna | transfer rna, carries the appropriate amino acid to the ribosome to be incorporated into the new forming protein. |
| Rrna | ribosomal rna, |
| peptide bond | formed between two amino acids |
| catabolism of carbs | glucose |
| catabolism of proteins | amino acids |
| catabolism of lipids | fatty acids |
| anabolism of glucose | glycogen |
| anabolism of amino acids | complex proteins |
| anabolism of fatty acids | complex molecules (steroids) |
| oxidation reaction | losing electrons |
| reduction reaction | gaining electrons |
| triphosphate | 3 phosphate |
| diphosphate | 2 phosphate |
| eukaryotes | multicellular organism |
| prokaryote | single cell organism |
