Biochemistry 86

Biochemistry is the study of chemical processes in living organisms, bridging biology and chemistry. Key topics include biomolecules (carbohydrates, proteins, lipids, nucleic acids), enzymes, metabolism, cellular respiration, and genetics. Each topic explores essential functions, structures, and processes vital for life at a molecular level.

Great!

Biochemistry is the branch of science that explores the chemical processes within and
related to living organisms. It’s where biology meets chemistry, helping us understand how life
works at a molecular level.

🔬 Main Topics in Biochemistry:


1. Biomolecules

These are the molecules essential for life:

Biomolecule Building Block Function

Carbohydra Monosaccharides (e.g., Energy source, structure (cell


tes glucose) walls)

Enzymes, transport, structure,


Proteins Amino acids
signaling

Energy storage, membranes,


Lipids Fatty acids & glycerol
insulation

Nucleic
Nucleotides (DNA/RNA) Store & transmit genetic info
Acids

2. Enzymes

 Biological catalysts that speed up chemical reactions


 Highly specific (lock-and-key or induced-fit models)
 Affected by temperature, pH, and inhibitors

3. Metabolism

The sum of all chemical reactions in the body:

 Catabolism – breaking down molecules for energy (e.g., glycolysis,


Krebs cycle)
 Anabolism – building up complex molecules (e.g., protein synthesis)
4. Cellular Respiration

How cells generate energy (ATP) from glucose:

1. Glycolysis
2. Krebs Cycle
3. Electron Transport Chain

5. Genetics & Molecular Biology

 Structure of DNA & RNA


 DNA replication, transcription (DNA → RNA), and translation (RNA →
protein)

Would you like help with a specific biochemistry topic (like enzymes, metabolism, DNA, etc.),
or do you want a diagram or study notes?
