Table K₁ (T1) Vmax (T1) Kt (T2) Vmax (T2) 1 1.12 mM 125 nmole/min None of the above. 3.0 mM 130 nmole/min Based on these values, what are your conclusions? O T1 is most likely a cell that expresses a high affinity transporter for glucose. T2 is most likely a cell that expresses a high affinity transporter for glucose. T1 must be a cell expressing the insulin-dependent glucose transporter. Each transporter has a similar Vmax and therefore both T1 and T2 are the same cell type.

What sort of cellular changes would you expect a sailor sick with scurvy to experience? O Their collagen (an extracellular matrix component) would be diminished, resulting in fewer binding sites for integrins. The end result would be less adherent cells. O Their collagen (a cytoskeletal fiber) would be diminished, resulting in a loss of contractile motion within the cell, affecting both cell migration and muscle function.

Which statements are true? Explain why or why not.1 The role of ATP hydrolysis in actin polymerizationis similar to the role of GTP hydrolysis in tubulin polym-erization: both serve to weaken the bonds in the polymerand thereby promote depolymerization.2 Motor neurons trigger action potentials in musclecell membranes that open voltage-sensitive Ca2+ channelsin T tubules, allowing extracellular Ca2+ to enter the cyto-sol, bind to troponin C, and initiate rapid muscle contrac-tion.3 In most animal cells, minus-end directed microtu-bule motors deliver their cargo to the periphery of the cell,whereas plus-end directed microtubule motors delivertheir cargo to the interior of the cell.
Below find the structures for ibogaine and cocaine. Ibogaine and cocaine inhibit the dopamine active transporter (DAT). This transporter is a secondary active transporter, and depends on the primary active transporter Na+/K+ ATPase. Ibogaine had a Kι = 2 μM, and cocaine a Kι = 0.64 μM respectively. (a) Define secondary active transport. (b) Is ibogaine an effective treatment for cocaine based on DAT binding?
Analogs of hemidesmosomes are the focal contact sites, which are also sites where the cell attaches to the extracellular matrix. These junctions are prevalent in fibroblasts but largely absent in epithelial cells. on the other hand, hemidesmosomes are prevalent in epithelial cells but absent in fibroblasts. In focal contact sites, intracellular connections are made to actin filaments, whereas in hemidesmosomes connections are made to intermediate filaments. Why do you suppose these two different cell types attach differently to the extracellular matrix?
