Answer:
Enzymes function best at specific pH and temperatures.
Explanation:
An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.
Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.
Hence, the correct statement about enzymes is that enzymes function best at specific pH and temperatures. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
Answer:
C.22 grams because mass cannot be created or destroyed
Explanation:
Reaction equation:
2H₂ + O₂ → 2 H₂O
Mass of oxygen = 18g
Mass of hydrogen = 4g
The mass of water produced is 22g according to law of conservation of mass.
The law states that " in a chemical reaction, mass is always conserved"
The sum of the mass of product and reactants must always be the same.
