Answer: P = 7.5 × 10^-17
Step-by-step explanation:
Given that the retraction speed = 1000nm/s
The mechanical power P exerted on the protein will be the product of exerted force F and the speed V. That is,
P = FV
Let consider the attached graph to solve the question.
The mechanical power P will be the area under the graph.
At V = 1000nm/s , F = 75 pN
Using the formula below
P = V × F
Substitute V and F into the formula
P = 1000 × 10^-9 × 75 × 10^-12
P = 7.5 × 10^-17 W
Therefore, the mechanical power exerted on the protein when the retraction speed is 1000 nm/s is 7.5 × 10^-17 watt.
