BIOL 325 Physiology Homework #4. Blood Typing, Memb. Potential and Hormones Name: Section: Instructions. Please complete the honiework using typing or clear handwriting. 1 (C pts) Fill in the Table below considering both ontigenic groups (ABO and Rn Blood Type Can Receive Whole Blood From … Can Donate Whole What antibodies could be here? Blood To A- B+ AB- 0+ )cannot have anti-Rh but a person without Rh antigen (Rh-) could have anti-Rh) 2)(4 pts) Using the values provided below and the simplified Nernst equation from lecture, fill in the table below assuming only facilitated diffusion of each of the ions below What will facilitated diffusion of the ions do to the membrane potential? ExtracellularCytosolicEquilibrium potential (mV) Depolarization or lon Na* Cl Ca2 K' hyperpolarization 140 mM 115 mM 2.5 mM 5 mM 10 mM 5 mM 100 nM 140 mM 3. (5 pts) The chemical properties of hormones restricts the manner in which they are handled. Assign the features below as primary characteristics of either the amino-acid based (AAB) hormones or the steroid (S) hormones hydrophobic hormones cell surface receptors for sensing hormone pass through the blood bound to proteins cross membranes through simple diffusion can remain stored inside cells have some protection from degradation in the blood are released very much like neurotransmitters cytosolic protein receptors _ cannot easily be stored in cells hydrophilic hormonesExplanation / Answer
1. If the blood group is positive, then D antigen is present in the blood.
2. Nernst equation can be simply written for each ion as
Ek = 61.54 * 10-3 log (Ko/Ki)
ENa = 61.54 * 10-3 log (Nao/Nai)
Ecl- = -61.54 * 10-3 log (Ko/Ki)
Eca = 30.77 * 10-3 log (Ko/Ki)
Blood group Antigens Donate to Receive From A- A A-, AB-, A+, AB+ A-, O- B+ B, RhD B+, AB+ B+, O+, B-, O- AB- AB AB-, AB+ A-, B-, AB-, O- O+ RhD O+, A+, B+, AB+ O+, O-Related Questions
