Study Notes
Organs and Their Locations
- Right Upper Quadrant contains liver, gall bladder, part of pancreas, part of stomach, and upper colon.
- Left Upper Quadrant houses the stomach, spleen, part of liver, and upper colon.
- Right Lower Quadrant includes small intestine, appendix, ascending colon, part of bladder, and reproductive organs.
- Left Lower Quadrant consists of small intestine, descending and sigmoid colon, part of bladder, and reproductive organs.
Requirements for Survival
- Water makes up 60–80% of body weight; it serves as a medium for metabolic reactions and helps maintain stable body temperature.
- Essential for nutrient absorption and oxygen/gas exchange.
- Nutrients and appropriate atmospheric pressure are vital for metabolic processes.
Chemistry and Biochemistry
- Matter is anything that occupies space and has mass; it can exist in solid, liquid, or gas states.
- Elements are the fundamental units of matter.
- Biochemistry focuses on the chemistry of living organisms, including their chemical characteristics and reactions.
Energy Concepts
- Energy is the ability to do work and can be stored in different forms (kinetic and potential).
- Nervous system requires the most energy among body systems.
- Energy cannot be created or destroyed; it can only be converted. Most conversions are inefficient, leading to energy loss.
Types of Energy
- Chemical Energy is stored in chemical bonds and released during reactions such as anabolism (building) and catabolism (breaking down).
- Electrical Energy powers the nervous system.
- Mechanical Energy is utilized by muscles.
- Radiant Energy includes sunlight, which travels in waves.
Chemical Reactions
- Involves making or breaking bonds between atoms, with total atom count remaining constant but reorganized.
- Types of reactions: Synthesis (A + B → AB), Decomposition (AB → A + B), and Exchange (AB + CD → AD + CB).
Factors Influencing Chemical Reactions
- Reaction speeds can be increased by temperature, particle concentration, particle size, and the presence of catalysts.
Inorganic vs. Organic Compounds
- Inorganic compounds lack carbon, are often small and simple; carbon dioxide (CO2) and carbon monoxide (CO) are exceptions.
- Organic compounds contain carbon, are typically larger and more complex, and include carbohydrates, lipids, proteins, and nucleic acids.
Lipids
- Triglycerides are the most abundant and concentrated energy source, made of fatty acids and glycerol.
- Phospholipids consist of glycerol, two fatty acid chains, and a phosphorus-containing group, forming cell membranes.
- Steroids are flat molecules with interlocking rings, used to form hormones, vitamin D, and bile salts.
Proteins
- Composed of amino acids with an amine group and acid group. Proteins serve various functions, including structure and catalyzing reactions as enzymes.
- Enzymes act as biological catalysts, increasing reaction rates without being consumed in the process.
Nucleic Acids
- Make up genes, composed of carbon, hydrogen, oxygen, nitrogen, and phosphorus. Major types include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) which are essential for genetic information.
