An antibody binds to an antigen with a Kd of 5 x 10-8 M. At what concentration of antigen will the fraction bound be (a) 0.2, (b) 0.5, (c) 0.6, (d) 0.8

1. 1.25x10^-8m

2. 5x10^-8m

3. 7.5x10^-8m

4. 2x10^-7m

Explanation:

This question requires us to find concentration of antigen at 0.2,0.5,0.6, and 0.8

At 0.2

= 0.2x(5x10^-8)/1-0.2

= (0.2 x 0.00000005)/0.8

= 1.25x10^-8m

At 0.5

0.5x(5x10^-8)/1-0.5

0.5x0.00000005/0.5

= 5x10^-8m

At 0.6

0.6x(5x10^-8)/1-0.6

0.6 x 0.00000005/0.4

= 7.5 x 10^-8m

At 0.8

0.8x(5x10^-8)/1-0.8

0.8x0.00000005/0.2

= 2x10^-7m

You need to post the picture if you're trying to get this answer

Used to water and cool climates, probably not thick coated or fluffy. they most likely have thin coats and have to survive to find food. sorry if this wasn't the answer you were looking for..: )
