Chapter 7 – Overview of the Cell – Lecture Notes
Cell- the smallest functional unit of the body.
Function: Exocytosis. Active transport of a product of the cell into the outer environment. Vice versa is endocytosis.
Chromosomes are condensed chromatids. Chromosomes only visible when undergoing division.
Nuclear envelope is double-layered.
Kreb's Cycle- aerobic. Conversion of sugar byproducts into units of energy.
Ribosomes are protein factories. Bounded to the ER or the nuclear membrane.
The ER synthesis proteins and lipids for formation of new cellular membrane part.
Golgi apperatus. Raw material from the ER is received here where it is processed then sent to the final destination.
Lysosomes break down cellular waste products into basic building materials.
Peroxisomes gets rid of toxic chemicals including hydrogen peroxide.
The cytoskeleton of the cell are microfilaments, intermediate filaments, and microtubules. Helps stabilize the cells and also act as freeways for movement of molecules formed by cellular processes.
