Outer membrane of mitochondria correct answers - contains porins= permeable to all molecules below 10 kDa - similar chemical composition to plasma membrane Inner membrane of mitochondria correct answers - primary site of ATP production - contains cardiolipin -80% protein - has cristae cardiolipin correct answers - makes the inner membrane impermeable to proteins - special phospholipid with 4 fatty acid chains # of cristae correct answers - varies with the energy needs of the cell...

Forced flexion of the cervical spine may tear which of the vertebral ligaments between C4-6? - Answer Ligamentum nuchae, facet joint capsule and maybe the posterior longitudinal Forced flexion of the cervical spine may stretch which of the vertebral ligaments between C3-5? - Answer The same ligaments as above, as well as ligamentum flavum which may be stretched but is unlikely to tear because of its elastic composition Hyperextension of the cervical spine from C4-6 or the lumbar spine fro...

Glycerophospholipids (GPLs): - amphipathic (having both hydrophilic and hydrophobic parts) are main lipid constituent of PM Contain glycerol backbone: 2 fatty acid tails in ester linkage A polar head group (that varies in size) A phosphate ester of another alcohol (choline, ethanolamine, serine, or inositol) GPLs can differ in polar head group, chain length, and saturation of bonds Common cell structures called organelles are either membrane bound or non membrane bound. Choose the follow...
