Study Notes
Metabolism Overview
- Metabolism consists of all biochemical reactions in a cell, first discovered by Gasket.
Types of Metabolism
-
Anabolism:
- Involves biosynthesis, requiring input energy.
- Transforms simple molecules into complex ones (e.g., glucose to glycogen).
-
Catabolism:
- Involves degradation and hydrolysis, releasing energy.
- Breaks down complex molecules into simpler ones (e.g., glycogen to glucose).
Lipids
-
Fatty acids serve as the monomer of lipids.
-
Lipase is the enzyme responsible for lipid degradation.
-
Triacyl Glycerol Structure:
- Composed of three fatty acids esterified to glycerol.
Chemical Properties of Lipids
- Acid Value: Measures the quality and age of fatty acids, reflecting the amount of free fatty acids present.
- Iodine Value: Indicates the degree of unsaturation in fatty acids by assessing iodine addition across double bonds.
- Saponification Value: Represents the amount of potassium salt of fatty acid produced from hydrolyzed glycerol.
Additional Information
- Rajigaza: A natural biopesticide.
- Smallest Electric Motor: ATP synthase stands out as the smallest electric motor known.
Redox Reactions
- Reduction: The process of gaining hydrogen ions (H+), providing reducing power.
- Oxidation: Involves the release of hydrogen ions (H+).
Electron Transport Chain (ETC)
- Cytochromes: Function as electron acceptors in the chain.
- NADH + H+ and FADH2: Produced through oxidation, they donate electrons and protons during the electron transport process to create ATP.
- ATP Synthase: Enzyme that facilitates proton flow into the mitochondria, leading to ATP production and release.
