L-3-Cell structure

Organelles of Animal Cells
Endoplasmic reticulum (ER)
Ribosomes
Golgi Body
Peroxisomes
Lysosomes
Mitochondria
Cell Nucleus

Functions of organelles
compartmentalize a cell’s activities
keep reactions isolated from one another
increase efficiency in the cell

Lysosomes (or suicide sacs)
Vesicles containing > 40 types of digestive enzymes
These enzymes are called acid hydrolases
The interior of lysosome is acidic (pH 5.0)
Function to recycle damaged organelles, break down cellular byproducts & destroy invading microbes

Mitochondria
double-membrane: outer is smooth inner is highly folded (cristae)
contain DNA, ribosomes
can grow and divide independently of cell division
mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP).
ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called aerobic respiration.
