A catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.
Catalysts increase the rate of reaction without being used up. They do this by lowering the activation energy needed. With a catalyst, more collisions result in a reaction, so the rate of reaction increases. Different reactions need different catalysts.
Many important chemical reactions require inputs of energy to proceed. If a catalyst is present less energy will be required to complete the reaction. Catalysts are substances that are mixed in with materials that are to be reacted, but they themselves do not, in the end, change chemically.
SO, a catalyst will increase the rate of reaction of any component.
Answer:
The impact on the loss in the activity of the OmpF proteins could alter the permeability of certain drugs thus avoiding the antibacterial effect. And a change or alteration in the ToIC protein could alter the transport capacity of certain harmful substances, thereby achieving hostile environmental conditions.
Explanation:
A modification in the OmpF porins would primarily affect the antibiotic drug line, including carbapenems and cephalosporins. A loss in the activity of the OmpF porins would favor resistance to antibiotics and to the change in the transport of molecules allowing the activation of expulsion pumps, resulting in the aforementioned resistance.
On the other hand, when the ToIC proteins are modified, a system that causes the antimicrobial drugs to be expelled would be activated, this system being known as exit pumps, however, this system does not transport some more hydrophobic beta-lactam beta or some aminoglycosides.
Answer:
matter and yes because I have to think of 20 words so yeah
Answer:
The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the most dense layer of the atmosphere
