Ch. 1 Flashcards
Anatomy is the study of
Structure
Physiology is the study of
Function
building block of protein and function of protein
- amino acid
- important part of cell structure and function
lipid building block and function
- no one building block for all lipids
- provides long term energy, is part of the lipid bilayer of cells (phospholipid), extracellular membrane facilitator of cell to cell interactions (glycolipids)
carbohydrate monomer and function
- Monosaccharide
- short term and long term energy storage (glycogen), structural attachment to protein for cell recognition,
Nucleic Acid monomer and function
- Nucleotide
- unit for heriditary information (DNA), protein biosynthesis (RNA)
Mad cow disease
- when people eat meat from and infected cow it can cause protein unfolding in the brain.
why is protein folding important?
Proteins are folded in a 3D shape to fit their function perfectly. If they are not folded correctly or unfolded, they loose their function.
characteristics of life
- energy consumption
-growth and repair
-adaptation/acclimation
-reproduction
what are the 3 components at least all cells have?
- membrane
- genetic material
- something floating in the cytosol
cell differentiation
The multiple steps of gene expression to make proteins for a specific cell function.
it is essential for the formation of many different cells.
4 types of tissue
- muscle
-connective
-epithelial - nervous
what are the 2 types of important surfaces of epithelial tissue
-apical
-basolateral
how are the surfaces of the 2 important epithelium formed?
- epithelial cells come together, organized by junctional proteins, and create segregated regions of plasma membrane.
where does the apical surface face?
the lumen of organs. the apical surface of the intestines contains carriers that allow ions and nutrients from the digestive system to the bloodstream.
