1. The following neurotransmitter neuromodulators are polypeptides; a) Aspartate b) Substance P c) Nitric oxide d) Acetylcholine e) Glutamine.

(ii) At the top, on the surface of the fluid acts the atmospheric pressure of 1.0x105Pa. If the volume V2 of the syringe shown is 200cm3 , determine the pressure on the fluid in the syringe (isothermal change).[4][12

) An IV drip container of volume, V1 =100cm3is placed 1.0m above the patient as shown. Determine the change in pressure of the fluid of density 1.9gcm-3 to the patient. [g=10ms-2] [4]

b. Briefly explain an application of specific gravity in determining the wellness of a Patient. [3]

Define specific gravity

Which of the following statements are correct about the peptide neurotransmitters? a. Peptide neurotransmitters are usually considered to initiate fast synaptic responses b. Large concentrations of peptide neurotransmitters are required for postsynaptic effects c. Large precursor molecules are transported from the nucleus to the nerve terminal where they are processed into peptide fragments constituting the peptide neurotransmitters d. Peptide neurotransmitters are usually directly secreted by the nerve terminal without being stored in synaptic vesicles e. Peptide neurotransmitters are limited to direct activation of ion channels
