Cell Function Flashcards
Plasma membrane
Maintain boundary and integrity of cells. Regulates what enters and exits the cell, anchor cytoskeleton, cell to cell communication.
Nucleus
Contains the genome, site of gene expression and DNA replication.
Nucleolus
Synthesis of ribosomal RNA and ribosome assembly.
Cytosol
Cell metabolsim (site of glycolosis)
Rough endoplasmic reticulum
Protein folding and initial post-translational processing.
Smooth endoplasmic reticulum
Carbohydrates and lipid synthesis. Detoxification site. Calcium storage in muscle cells.
Golgi Apparatus
Post-translational processing, packaging and sorting of proteins.
Mitochondria
ATP synthesis, metabolism of glucose and fatty acids, role in apoptosis (intrinsic pathway)
Lysosomes
Breakdown of cellular macromolecules and engulfed extracellular material.
Lysosomes
Breakdown of cellular macromolecules and engulfed extracellular material.
Peroxisomes
Reduction of reactive oxygen species (hydrogen peroxide), oxidation of fatty acids.
Ribosomes
Translation of mRNA to synthesize proteins.
Centrosomes
Organization and anchoring of microtubules, organization og mitotic spindle during cell division.
Microfilaments
Shape and movement of the cell, cytokinesis, muscle contraction.
Microtubules
Structural role, movement of chromosomes (cell division), movement of organelles and vesicles through motor proteins. Components og cilia, flagella and centrioles.
