Study Notes
Characteristics of Life and Organization
- Characteristics of life include cellular organization, growth and development, metabolism, homeostasis, response to stimuli, reproduction, and adaptation.
- Life processes are carried out by specific functions of body systems, such as movement, respiration, digestion, absorption, circulation, assimilation, and excretion.
- Structural organization in the human body ranges from atoms to organ systems, with increasing complexity.
- Tissue types differ in structure and function, including epithelial, connective, muscular, and nervous tissues.
Cell Structure and Function
- Prokaryotic and eukaryotic cells differ in their structures (e.g. nucleus and organelles), functions, and organization.
- Plant and animal cells exhibit specific structural variations.
- Plasma membranes in eukaryotic cells have a specific organization with different components (e.g. proteins, phospholipids).
- Cytoskeletal elements (e.g. microtubules, intermediate filaments, microfilaments) play various roles in cell structure and function.
- Mitosis and meiosis are involved in cell division, with notable stages and physiological significance.
- Key cellular molecules include carbohydrates, proteins, lipids, and nucleic acids. These molecules have specific structures and functions in the cell.
- The characteristics, actions, and functions of enzymes are also important for cellular processes.
- Active and passive transport are mechanisms for molecules to move across the cell membrane. Their roles in maintaining cellular balance are important.
Overview of Human Physiology
- The various systems in the human body have several major functions:
-
Digestive system processes, digests, and absorbs nutrients.
-
Respiratory system exchanges gas.
-
Circulatory system brings blood, lymph, and regulates cardiac activity, blood pressure and related diseases.
-
Excretory system processes and excretes waste products.
-
Musculoskeletal system allows for movement, and its components work together.
-
Nervous system processes sensory information and controls bodily actions.
-
Endocrine system produces hormones that regulate various bodily functions.
-
Genetics and Molecular Biology
- Mendelian inheritance and the chromosome theory describe how traits are passed from parent to offspring, based on genes located on chromosomes.
- Gene interaction encompasses how gene actions affect each other.
- Concepts like incomplete dominance, codominance, and multiple alleles influence genetic expression.
- Genetic information transfer and regulation explain gene expression through various biological processes.
- Human molecular genetics has medical applications including genetic engineering and diagnostics.
