Document Summary

Animal cells have much longer mitochondria; look more filamentous and tubular; varying shapes and sizes. E(cid:374)e(cid:396)gy (cid:396)elease (cid:272)a(cid:374) take pla(cid:272)e outside the (cid:373)ito(cid:272)ho(cid:374)d(cid:396)ia (cid:271)ut it"s lo(cid:449)-order energy (only get ~ 2 atp) Mitochondria release trapped energy from glucose (in the form of atp) to be used to fuel the cell: high return in atp get 36 from 1 glucose molecule. Characteristics: 5 10% of cell volume, about 10 um diameter typically one/ cell. Functions: storage, replication and repair of genetic material, expression of genetic material (most- also some in mitochondria of animal cells, and mitochondria and plastids in plant cells) ribosome biosynthesis. Structure: nuclear envelope, nuclear membrane, nuclear lamina support, nuclear pores, nuclear content: chromatin (dna and protein, euchromatin expressed, other chromatin though tot aid in stability, nucleoplasm, nuclear matrix scaffolding, nucleolus. Nuclear envelope (ne): structure, 2 parallel phospholipid bilayers 2 layers are connected to er (usually rer, outer membrane: binds ribosomes and is continuous with rer.
