The product NADH is used as a reducing agent to donate the electrons in the electron transport chain.

On, the basis of the above information the statement the coenzyme, NAD, is responsible for transporting hydrogen is true.

In a study of proteins mediating cell membrane transport, microbiologists measure current versus time through the cell membranes
MrRa [10]

Answer:

Q(0) = 0C, Q(1) = 264nC, Q(2) = 952C Q(3) = 2088nC, Q(4) = 3696C Q(5) = 5800nC

Explanation:

I = 4t³ + 200t² + 60t

But charge of an object =》 Q = IT

Charge of an object is the product of the current and the time in which the current passes through the membrane.

When t = 0

Q = 4(0)³ + 200(0)² + 60(0) = 0C

When t = 1

Q = 4(1)³ + 200(1)² + 60(1) = 264nC

When t = 2

Q = 4(2)³ + 200(2)² + 60(2) = 952nC

When t= 3

Q = 4(3)³ + 200(3)² + 60(3) = 2088nC

When t= 4

Q = 4(4)³ + 200(4)² + 60(4) = 3696nC

When t = 5

Q = 4(5)³ + 200(5)² + 60(5) = 5800nC
