Answer:
Explanation:
Hello,
In this case, given that 1 kilometer equals 1000 meters, 1 meter equals 3.281 feet and 1 hour equals 3600 seconds, the required velocity in feet per second turns out:
Regards.
Kinetic energy is the speed at which molecules or atoms move dependent on the temperature and state of matter
statement about enzymes that is correct is
b. they are large molecules that increase the rate of biologically important reactions
Enzymes are proteins that catalyse, in other words increase the rate of the biological reactions.
Biological functions that are vital for the bodies to survive, have large activation energy barriers. For this reason enzymes are used that reduce the activation energy required for the reaction to initiate. this enables the reactions to proceed.
Substrates bind to the enzyme, reaction occurs and substrate converts to products, that are released from the enzyme, leaving the enzyme unchanged.
so the correct answer is B.
