Study Notes
Centrioles
- Centrioles are involved in the formation of cilia and flagella and are responsible for the movement of cilia.
- They are typically located near the nucleus and are involved in organizing the microtubules of the cytoskeleton and are important for cell division.
- Centrioles are not found in muscle cells.
Flagella
- The primary function of flagella in cells is to facilitate movement.
Cilia
- Motile cilia are primarily found in the respiratory system.
- The main function of primary cilium is to sense the environment and provide feedback to the cell.
Nucleus and Cytoplasm
- Chemical communication between the nucleus and cytoplasm takes place at nuclear pores.
Protein Synthesis
- The primary function of ribosomes is to synthesize proteins.
- Free ribosomes are located throughout the cytoplasm, while fixed ribosomes are attached to the endoplasmic reticulum.
- The genetic information for protein synthesis is encoded in mRNA.
- Translation involves reading the mRNA nucleotide sequence to determine the amino acid sequence of a protein.
- mRNA is synthesized during transcription for protein synthesis.
- Aminoacyl-tRNA brings additional amino acids for protein synthesis.
- Ribosomes are responsible for protein synthesis and are primarily involved in this process in the cytoplasm.
Endoplasmic Reticulum
- The primary function of rough endoplasmic reticulum is to synthesize proteins.
- Fixed ribosomes are attached to the rough endoplasmic reticulum.
Golgi Apparatus
- The primary function of Golgi vesicles is to modify and package proteins synthesized by the rough endoplasmic reticulum.
- Golgi vesicles are involved in assembling and modifying ribosomal subunits before they are functional.
Lysosomes
- Lysosomes contribute to cellular function by degrading and recycling cellular waste and foreign substances.
Proteasomes
- The main function of proteasomes is to degrade damaged or misfolded proteins.
Peroxisomes
- Peroxisomes generate hydrogen peroxide and have the enzyme catalase to protect the cell from free radicals.
Nucleoli
- The main function of nucleoli is to synthesize ribosomal RNA.
- Ribosomal RNA is directly involved in protein synthesis at the ribosome.
- The nucleolus is responsible for the production of ribosomal RNA.
Centrosome
- The function of the centrosome is to organize microtubules and facilitate cell division.
