An average platelet is a cylinder 2 um in diameter and 0.2 m in height. platelets have approximately 75,000 integrin molecules on their membrane surface. if each integrin molecule is represented as a cylinder that is 10 nm in diameter, what percentage of the platelet surface area is covered by integrins?

93.75 %

Explanation:

Base surface area of a cylinder is given by

where r is the radius and h is the height

The surface area of platelet is

\\ 2 * 3.14* (\frac{2*10^{-6}}{2})^2\\ 6.28*10^{-12}\\6.28 *10^{-12}" alt="2(pi)r^2" />\\ 2 * 3.14* (\frac{2*10^{-6}}{2})^2\\ 6.28*10^{-12}\\6.28 *10^{-12}" />
