HONR 1033 Lecture Notes - Lecture 1: Keratin, Antibody, Nuclear Membrane
Document Summary
The fundamental units of life - cells and molecules. I. biology- the study of life: properties of life: 1. order, evolutionary adaptation, regulation, reproduction, response to the. 2. cells require structure to create life: otherwise meaningless; think pointilism environment, growth and development, energy processing. Disaccharides (lactose); must be hydrolyzed" to be processed/digested. 3. lipids- fats, phospholipids (major constituents of cell membranes), steroids- cholesterol; necessary to synthesize hormones. 4. nucleic acids- polymers of amino acids, four levels of structure: primary, beta sheet or. Functions (bc of unique structure): insulin-regulates sugar, actin and myosin- allow for contraction/movement, hemoglobin- bonds oxygen to blood cells (transport), keratin- hair and skin, antibodies- fight diseases. C. what is a cell? protozoan, green algae, yeast, bacterial cell life. 1. cell- basic structural and functional unit of any living organisms: such as; nerve cell, 2. prokaryotic cell- absence of nuclear envelope: exists in nuclei, make up basic units of. 3. eukaryotic cell- has a nucleus except for red blood cells (so can carry more.
