Exam 2 Flashcards
(23 cards)
Vacuoles
found in plants usually, but used for selective storage
Nucleus structure
Double membraned with a black nucleolus inside it.
Types of prokaryotes
Archaea and Bacteria
Ribosomes
Protein synthesis
Rough Endoplasmic Reticulum
Protein synthesis
What makes up the nuclear lamina?
Intermediate Filaments
What organelles do all cells have?
Nucleus/Nucleoid, ribosomes, cytoplasm, and plasma membrane
Golgi Apparatus
packages up products of the cell to go somewhere else in the cell or out of the cell
Cytoplasm
Semi-Fluid Matrix that holds organelles
Plasma Membrane
Phospholipid bilayer that controls cell traffic
Nucleus
The storage unit for DNA
Amphipathic
has both hydrophobic and hydrophilic parts
Lysosome
Breaks down waste and food in the cell
Endomembrane System
It’s the secretory system, aka the system that functions to create, process, and deliver proteins. It includes, the nucleus, ER, lysosomes, golgi apparatus, plasma membrane
Material in Prokaryotic cell walls
Peptidoglycan- Proteins + Carbohydrates
Flagellum
The method of movement for many cells (primarily bacteria). Moves via rotary movement.
Peroxisomes
oxidizes fatty acids makes H2O2 that’s neutralized by catalase
Smooth Endoplasmic Reticulum
Lipid synthesis
Cell Theory
- Cells are the smallest living things
- All organisms are made from cells
- Cells arise from pre-existing cells (LINE OF DESCENT)
Bulk transport
Endocytosis: into the cell
Exocytosis: out of the cell
Moving large molecules in or out of the cell (ie. polysaccharides and proteins)
Catabolic Reaction
Exergonic reaction that uses energy to break down a large molecule into smaller parts. EXERTS energy
Anabolic Reaction
Endergonic reaction that does not use energy and is used to build larger molecules from smaller ones.
