It's main function is to produce ATP, the energy currency of the cell. The mitochondria take fuel (glucose) and essentially burns it. The energy given off by oxidizing the fuel is harnessed by causing ions to move across a membrane, kind of like pumping water. The ions then flow down through a protein which synthesizes ATP much like the water then flows down through a dam to generate electricity.
they have specialised cells ?
Answer:
yes
Explanation:
Even though both parents still have blood type A, Dad can pass on either his A or his O gene version. Mom can also either pass on her A or her O. Because of this, you can see that there's 1 in 4 or 25% chance for a child to have blood type O.
The factor that is responsible for the phenomenon of the blood group B being almost absent in Native Americans whose ancestors arrived in very small numbers about 10,000 years ago would be called the 'founder effect'.
