Metabolism Flashcards
Name sources for ATP in muscles:
a) creatine phosphate
b) glycogen (glycolysis - lactic acid)
c) cellular respiration
What is anabolism.
Synthesis of new molecules, by consumption energy. Endergonic process and involuntary.
What is catabolism.
Break down from lagert into smaller molecules, by releasing of energy. Exergonic process, voluntary.
Explain metabolism.
sum of all chemical reactions in living organism, for the cell to grow, to reproduce and to maintain structures against changes in environment.
Stages of catabolism.
- Hydrolysis of complex molecules into their building blocks, ex. proteins into amino acids.
- Conversion into acetyl-CoA.
- Oxidation acetyl-CoA - ATP production by oxidative phosphorylation.
How many reactions necessary in Glycolysis?
10 reactions, 3 irreversible.
How many reactions necessary in Gluconeogenesis?
11 reactions, 4 irreversible.
Explain in short what is Gluconeogenesis?
Gluconeogenesis is the synthesis of glucose form other sources than carby.
Pyruvate and lactate (60%)
Aminoacids (20%)
Glycerol (20%).
Name three monosaccharide.
Glucose, Fructose, Galactose.
Name three Disaccharide.
Maltose, Sucrose, Lactose.
Name three Polysaccharide.
Starch, Glycogen, Cellulose.
Characteristics of Saccharide.
- Low MW.
- water-soluble.
- sweet to taste.
Characteristics of Polysaccharide.
- High MW.
- water-insoluble.
- testeless.
Aldoses.
Monosaccharide with an aldehyde group.
Ketose.
Monosaccharide with a ketone group in its structure.
Explain the digestion of carbohydrates.
