Study Notes
Biochemistry and Life Processes
- Biochemistry serves as a key to understanding human body functions and life processes.
- Complex organisms, including humans, are composed of diverse and complex cells.
- Interdisciplinary nature of biochemistry allows integration of insights from multiple scientific fields.
Applications in Health Sciences
- Knowledge of molecular health and disease enhances treatment efficacy across various illnesses.
Cellular Organization
- Cell activities can be likened to a city's transportation system, where molecules act like vehicles.
- Prokaryotic and eukaryotic cells differ significantly in structure and organization.
Prokaryotic and Eukaryotic Cells
- Prokaryotic cells lack membrane-bound organelles, while eukaryotic cells possess them.
- Prokaryotic DNA is organized without a nucleus, and there are differences in the nature of their cell walls.
Cellular Structures
- Plasma membrane serves as the boundary separating the cell from its environment, composed of lipids and proteins.
- Prokaryotic cells are often encased in a rigid cell wall made primarily of polysaccharides, providing protection.
- Mitochondria are energy-producing organelles found in eukaryotic cells, containing their own DNA and ribosomes resembling those in bacteria.
Endoplasmic Reticulum (ER)
- The endoplasmic reticulum is a single-membrane system that forms a network throughout the cell.
- Rough ER is distinguished by ribosomes, while smooth ER lacks them, serving different functions within the cell.
