An enzyme is discovered that catalyzes the chemical reaction SAD ↔ HAPPY A team of motivated researchers sets out to study the enzyme, which they call happyase. They find that the kcat for happyase is 600 s-1. They carry out several experiments and found that, when [Et] = 20 nM and [SAD] = 40 μM, the reaction velocity, V0, is 9.6 μM s-1. The Km for the substrate SAD is μM .

The of a substrate will be "10 μM".

Explanation:

The given values are:

Reaction velocity,

As we know,

⇒  

On putting the estimated values, we get

⇒  

⇒  

⇒  

On subtracting "40" from both sides, we get

⇒  

⇒  

a small container that holds a source of energy a solar cell that captures light energy and converts it into electricity a voltaic cell that uses the oxidation of a fuel to produce electricity

explanation:

the answer is barium and copper bromide
