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 |
