Lecture 1 Flashcards
4 common things between prokaryotes and eukaryotes
DNA, ribosomes, cytoplasm, cell membrane
What is sructure slosely related to?
Function
How do cells receive messages?
ligands on receptors
4 things that the metabolism does
- convert food into energy
- convert food into building blocks
- buils and repairs cellular structures
- eliminates waste
8 key characteristics of living entities
- high cellular organisation
- response to stimuli
- homeostasis
- metabolism
- autonomous reproduction
- growth and development
- heredity
- adaptation to environment through evolution
3 parts of cytoskeleton
microtubules (involved in cell division, transport, cell shape)
actin filaments (move and cell division)
intermediate filaments (resist tension)
4 functions of transmembrane proteins
transporter, receptor, enzyme, anchor
3 cell nucleus structures
nucleosol (liquid and chromatin), nuclear skeleton, nucleolus (ribosomal RNAs)
smooth and rough ER roles
smooth = lipid and steroid production
rough = synthesis, folding, modifications of proteins
golgi role
protein modifications and packages them into secretory vesicles
3 protein destinations
cell membrane, extracellular space, lysosomes
what do peroxisomes digest ?
lipids
