Show how the structure of glycogen and cellulose, is related to its function in each case?

Which is true about starch versus cellulose? They have different properties because their building blocks are very different They have similar properties because their building blocks are very similar They have different properties due to subtle differences in their building blocks They have similar properties despite subtle differences in their building blocks

Fibre is generally not digestible byhumans• C. cellulose is an insoluble fibre that can form extensive hydrogen bonds• D. Fibre provides structure in stems and trunks of plants

7) You encounter a bunch of cells with glucose concentration inside of 0.10 mM and they are suspended in a solution that has a glucose concentration of 0.010 mM. ww a) Will glucose travel into or out of the cells? b) What is the free energy change in kl/mol for the transport of glucose from the medium into the cell? Assume a temperature of 37 °C. 8) Explain why DNA with a higher ratio of A-T base pairs compared to G-C base pairing would have a lower melting point. 9) Ethidium bromide is a compound commonly used to visualize DNA during gel electrophoresis, though its use has been phased out due to toxicity and mutagenic concerns. This compound stains DNA by intercalating. Explain what this means in the context of DNA base pairs.
