Look at the graph of reaction rate versus substrate concentration for an enzyme. In which region does the reaction rate remain c

OleMash [197]

Answer:

The correct answer is C.

Explanation:

The reaction speed remains constant in region C. This is because the growth rate decreases, tending to zero. Graphically you can see how the slope of the tangent line approaches the horizontal. The slope of the tangent line represents the rate of reaction speed. It is constant because although the concentration continues to increase, the reaction rate does not vary.

Have a nice day!

Convert 3.00 x 10^5 km/sec to miles/hr. (1 mile = 1.609 km)

SVETLANKA909090 [29]

Answer:

$3\times 10^5\ \dfrac{km}{s}=6.71\times 10^8\ \text{miles per hour}$

Explanation:

In this problem, we need to convert $3\times 10^5\ km/s$ to miles per hour

We know that,

1 mile = 1.609 km

1 hour = 3600 seconds

$3\times 10^5\ \dfrac{km}{s}=3\times 10^5\dfrac{(\dfrac{1}{1.609}\ \text{miles})}{\dfrac{1}{3600}\ \text{hour}}\\\\=6.71\times 10^8\ \text{miles per hour}$

Hence, $3\times 10^5\ \dfrac{km}{s}=6.71\times 10^8\ \text{miles per hour}$
