Chapter 3 The Cell Flashcards
What type of solution will cause a cell to undergo crenation ?
Hypertonic
If a cell was placed in a hypotonic solution, what would happen ?
Lysis ->cell burst
What does the sodium potassium pump do ?
Expels sodium out and brings potassium in, this is important to maintain cell volume
Type of bulkphased endocytosis that ingests tiny droplets of ECF
Pinocytosis
Network of protein filaments that extends throughout the cytosol and provides a structural framework for the cell
Cytoskeleton
Tiny finger like projections of plasma membrane that increases surface area of cell
Microvilli
Type of protein filament that determine cell shape and function
Microtubules
What is a perioxosome?
Similar to lysome but smaller, contain oxidase that will oxidize organic substances
What is a proteosome?
Destroy damaged unneeded or faulty protein
What are the phases of interphase ?
G1
S phase
G2
What produces ribosomes ?
Nucleoli
True or false. Mitochondria have their own DNA
True
Total genetic info carried in a cell or organism
Genome
What happens first transcription or translation ?
transcription
What happens in transcription ?
Information is encoded in a area of DNA and copied to produce a specific molecule of RNA
