Enzymes decrease the activation energy, Enzymes increase the rate of the reaction, Enzymes provide a site where reactants can be brought together.
Enzymes are like catalysts which enhance the rate of reaction by lowering the activation energy.
All the biochemical reactions are slow because of transition state barriers. These transition state barriers are an intermediate state before the formation of products. Transition state is a high energy state and it requires a lot of energy to cross this state but we can not produce this much energy in our body. That is why an enzyme is must to catalyze any bio-chemical reaction because enzyme provides an alternate pathway which requires very low energy to proceed.
Enzymes have certain active sites wherein substrates fit in and interact with each other with the help of their functional groups and interaction of these substrates subsequently leads to product formation.
As the human population increases the demand of resources will also increase . As we all know that it takes million of years to replenish resources. so if human will use it continuously it will be wipe out from the earth and there are no resources left for future generation. And for this prblem Sustainable is setup by the government..
Chaparral is confused with the desert because they share many similarities such as both being hot and dry. The chaparral receives more rainfall per year than the desert.
Cell division is when a cell under goes mitosis. Which divides in top to create another cell of the same kind. In Gamete a haploid germ of either sex unites with the opposite sex to have sex and have a zygote.
