• is the loss of density in the bone; compared to lost of cartilage
• no bony spurs produced
• in crease chances of fractures, which is not an affect on osteoarthritis

Modifies proteins and packages proteins for use
What is in the fluid mosaic?

• electron transport chain - 34 ATP
What are reason why muscles are greatly affected by a mitochondrial disease?

How can ineffective mitochondria affect general function of the body?

How does the blockage in the opening of the small intestine effect the digestive function?
When the duct is blocked it becomes difficult for food, and minerals to pass through the intestines, causing it to have a lack absorption of beneficial nutrients also results to the decrease of breakdown of lipids.
