BIOL-N - Biology BIOL-N 261 Chapter Notes - Chapter 2 : Mitochondrion, Mitochondrial Matrix, Atp Synthase
Document Summary
Organelle = small organ: are small, cellular structures suspended in the cytosol. The cytoplasm: consists of three major elements. An intercellular fluid that contains dissolved solutes, and surrounds the cellular organelles: organelles. Specialized subunits within a cell that has specific functions: membranous organelles. Separately enclosed within their own lipids membranes that isolate them from the cytosol. Mitochondrium (plural=mitochondria: bean-shaped organelles, which are describe as (cid:862)cellular power plants(cid:863) (cid:271)e(cid:272)ause they ge(cid:374)erate (cid:373)ost of the (cid:272)ell"s supply of atp (95% of the supply) used as a source of energy, consists of two membranes. The outer mitochondrial membrane, which encloses the entire organelles. The inner mitochondrial membrane that folds inward to produce cristae, which increases the surface are and enhance the organelles ability to produce atp. Mitochondrial matrix - the space enclosed by the inner membrane. Atp with the aid of the atp synthase contained in the inner membrane.
