please show work ! will thumbs up!

Short answer questions. Write your answers to these questions on blank paper. When you are ready to submit your exam, show your answers to your camera. Submit the exam, then scan and upload your work as a single pdf file. 1. (12 points Using Haworth projections, draw the structure of an a-disaccharide of mannose (1,2) galactose (mannose is the C-2 epimer of glucose, galactose is the C-4 epimer of glucose). Draw the structure of His as it would occur at pH 7 and show one interaction that would occur between C4 of galactose and the R-group of His (use a dotted line to indicate the interaction). What type of interaction is this? 2 (5 points) Draw the structure of the fatty acid, 16:2710, as it occurs at pH 7. Make sure double bonds have the correct configuration. Using the omega numbering system for fatty acids, what type of fatty acid is this? 3. (7 points) Draw a diagram that shows the formation of the sodium gradient using ATP coupled to active transport of glucose using the sodium gradient. Clearly label the sides of the membrane and transporter(s) used. Clearly show the direction of ion/molecule movement and the number of ions/molecules moving 4. (4 points) The following curve shows typical hemoglobin to oxygen binding. Draw the curve on your paper, then draw and clearly label curves for hemoglobin-oxygen binding following (1) decreased CO2 and (2) decreased pH. 2. (5 points) Draw the structure of the fatty acid, 16.227,10, as it occurs at pH 7. Make sure double bonds have the correct configuration. Using the omega numbering system for fatty acids, what type of fatty acid is this? 3.
