What is hydrocephalus? Correct Answer-Hydrocephalus is the excessive accumulation of CSF that increases intracranial pressure. -Blockage in flow of CSF through ventricles of brain or when cannot be absorbed by arachnoid villi. What types of substances are able to directly cross the blood-brain barrier? Correct Answer-Lipophilic substances are able to cross the blood-brain barrier directly and enter the brain. *Water crosses membrane by simple diffusion. Most nutrients cross blood brain barr...

Entry in from gram negative OM CORRECT ANSWER 1. Diffusion - not selective via porins 2. Facilitated diffusion - more specific porins 3. Energy coupled transport- use ATP to actively transport porin across. Entry into the cell CORRECT ANSWER 1. Simple diffusion - not very hepful 2. Facilitated diffusion - selective channels 3. Concentration gradient - no E input 4. Ion coupled - transport coupled to ionic gradient. E used to set up gradient. Transport bi directional. 5. ABC - binding p...
