1. You are studying a new organism from the muck at the bottom of Columbia Lake,which you have named Ipso facto. I. facto is able to take up ribose from the growthmedium by the ribose transport protein (RTP). Your data indicates that the ribosethat is taken up is converted to ribose-5-phosphate (R-5-P) as it is transported intothe cell, and the phosphate on the R-5-P is from ATP. The uptake of ribose is notinhibited by compounds that inhibit the Na+-K+ATPase (the Na+-K+ pump).

1a. What type of transport is used to take up the ribose in I. facto? In your answer,explain all the data. What is the source of energy for the transport of the ribose?Support your answer.

1b. Draw a schematic of the RTP in the membrane, showing the various individualstepsin ribose transport. Be sure to indicate where the membrane is, the insideand outside of the cell, and how the ribose is converted to R-5-P? In youranswer, show the transport process (the answer here is more complex than adrawing of hole in the membrane). For the next part of your answer, show adetailed chemical mechanism for the conversion of ribose to R-5-P by ATP
