are enzymes carbohydrates
No, they speed them up by lowering the activation energy of reactions. The body has other ways to slow reactions. Concentration of enzymes, inhibition of enzymes, sometimes by negative feed back mechanisms.
Chemical reactions involving enzymes slow down when the temperature is too high or too low, as enzymes have an optimal temperature range for activity. Additionally, changes in pH levels can also affect enzyme activity, causing reactions to slow down. Lastly, the presence of inhibitors or competitive molecules can hinder enzyme function, leading to a slowdown in reactions.
No, they act as a catalyst and help reactions occur
Some proteins act as enzymes, yes. Enzymes are just proteins that catalyze (speed up/slow down) reactions.
Preservatives slow down spoilage of food. Preservatives can prevent or slow microbial growth, prevent or slow the action of degrading enzymes, and slow down other negative reactions in food.
In biological chemical reactions, examples of these are called enzyme inhibitors. Enzymes speed up reactions, but enzyme inhibitors slow them down. This can be by either competing with the reactants for a spot on the enzyme, or by altering the enzyme's structure so that it does not speed up reactions anymore. In either case, enzyme inhibitors slow down chemical reactions.
No, the sole purpose of enzymes are to increase the rate of a chemical reaction. Even if they are not at an optimal temperature, they will not slow down the reaction. They won't work as efficiently, but it will still be slightly faster than without the enzymes.
enzymes are the catalyst that aid the reactions taking place inside our bodies. if there were no enzymes, our metabolic processes would slow down to such a rate that we would not be able to survive.
Temperature can impact the process of photosynthesis by affecting the enzymes that are involved in the chemical reactions. Higher temperatures can increase the rate of photosynthesis up to a certain point, but too high temperatures can denature the enzymes and slow down or stop the process. Conversely, lower temperatures can slow down the rate of photosynthesis as the enzymes work more slowly.
Careful! Not all enzymes are hydrolytic. Hydrolytic enzymes catalyse reactions in which there is breaking of molecules (involving the participation of water molecules). There are enzymes which catalyse reactions in which molecules join together to form a larger molecule (condensation reactions)
yes they can
Enzymes can catalyze reactions such as oxidation-reduction, hydrolysis, condensation, and isomerization. They can also facilitate reactions involving the transfer of functional groups or rearranging molecular structures.
