SI Leader: Anita Vijapura Spring 2010 BSC2011 1/25/10-1/28/10 1 Gas Transport Using the information in the picture, explain what happens in gas transport. Describe the limitations of the transport of O 2 to the cells? What is the oxygen carrying capacity of blood (w/o a transport pigment)? What is a transport (respiratory) pigment ? A transport pigment consists of a ________________ attached to a _________________. Common transport pigments: 1. a. Components: i. ii. b. What organisms? 2. a. Components: i. ii. iii. b. What organisms? Main differences between Hemocyanin & Hemoglobin : 1. Metal: 2. Molecule type:

Unformatted text preview: 1. Hcy: 2. Hb: Myoglobin : 1. Function : 2. Structure : 3. Location : 4. Organisms : When myoglobin used as a source for oxygen? when Hb cannot deliver oxygen to the tissues rapidly enough. Why is red meat red? Myoglobin forms pigments responsible for making meat red: raw meat (Fe+2 – O 2 ) *FUN FACT: High concentrations of myoglobin in muscle cells allow organisms to hold their breaths longer. Main differences between Hemoglobin and Myoglobin: 1. Function : 2. Structure : Why is there a limit on the number of transport pigment molecules that the blood can contain? B/c transport proteins may increase viscosity and osmolarity But there are solutions: 1. 2. a. Limitations: b. Advantage:...
