Enzymes are carbohydrates that act as catalysts in metabolic reactions true or false?
FALSE!Enzymes are PROTEINS that can act as catalysts in metabolic reactions.
Catalyst are always enzyme it's true or false?
False . Catalysts can be many things ; enzymes and transition elements and their compounds , for example .So Enzymes are always catalysts but Catalysts are NOT always enzymes .
True or False Enzymes are inorganic catalysts?
False. The activation energy of the reaction remains the same. Enzymes split up the reaction pathway into fewer steps, so that less activation energy is required at each step. This allows each step to occur at a lower temperature, or more quickly at the same temperature.
What proteins act as catalysts in mediating and speeding specific chemical reactions?
True or False? Genes are the key to almost everything that living cells do. True or False? Genes are the key to almost everything that living cells do.
Enzymes tend to raise the activation energy?
Enzymes lower the amount of activation energy required. This makes the reaction more likely to occur and speeds it up as well.
Do enzymes work by providing energy to initiate reaction?
No they do not supply energy to start a chemical reaction, however energy has something to do with it. Enzymes actually lower energy barriers, in other words it reduces the activation energy needed which is the energy absorbed before the chemical reaction can start.
Do catalysts change during a reaction?
No
CFCs are the catalyst in the destruction of Ozone. true or false?
CFC's are catalysts. They fasten the rate of reaction.
Do enzymes affect the thermodynamics of a reaction true or false?
Enzymes have no effect on the overall thermodynamics of a reaction.
Is this true or false Four major types of macromolecules are proteins carbohydrates lipids and glycerol?
false
Starches and sugars are examples of carbohydrates true of false?
True.
IS it true that enzymes increase the number of collisions in a chemical reaction?
No that is false. Enzymes do NOT increase number of collisions in a chemical reaction.
