Simora [160]

Answer:

a. add more of the enzyme

Explanation:

Enzymes have specific sites to which their substrates bind during the reaction. These sites are called active sites. When all the active sites of all the enzyme molecules present in a solution are bound to the substrate molecules, the enzyme is said to be saturated with the substrate. Under these conditions, more enzyme molecules are to be added to the solution to increase the reaction rate and to obtain the product at a fast rate. The addition of more enzymes will allow more substrate molecules to occupy the active sites and to be converted into the product/s.

Give ONE suggestion for how humans can lessen their impact on Earth.
lora16 [44]

Answer:

Humans must decrease the harmful impact they have on earth or else the human population could go extinct forever. One way to do this is to inform the people on climate change and its effects. Recycling, using metal straws, carpooling, cleaning up beaches, pulling unncessary plugs in your house to reduce electricity usage, and doing so much more can help reduce the risk of climate change and help the world become a much healthier and stable place for humans, plants, animals, and the environment.
