Study Notes

Metabolism consists of all biochemical reactions in a cell, first discovered by Gasket.

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).

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.

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.

Rajigaza: A natural biopesticide.
Smallest Electric Motor: ATP synthase stands out as the smallest electric motor known.

Reduction: The process of gaining hydrogen ions (H+), providing reducing power.
Oxidation: Involves the release of hydrogen ions (H+).

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.
