This is common sense! Blood
What your cells have to help overcome a problem of high activation energy are called enzymes. Enzymes are proteins that lower the activation energy of a reaction. In doing this, enzymes increase the rate of a reaction, helping it to occur faster. However, enzymes are not consumed in a reaction; they simply help it to occur.
Enzymes make things easier for your cells to work properly and help chemical reactions occur. There are hundreds of different kinds of enzymes in your cells, which all participate in different types of reactions. Enzymes can break molecules apart, build or add molecules, and even rearrange them.
In lowering the activation energy of a reaction, enzymes decrease the barrier to starting a reaction. It's important to note, however, that the change in energy remains the same between the start and end of a chemical reaction.
Answer:
Blood flow!
Explanation:
Blood flow is the volume of blood flowing through any given vessel, or through the circulatory system as a whole, per minute. This is also called cardiac output, and it's determined by the blood volume pumped during one beat and the number of beats per minute.
Hope this helps! :3
The answer to that will be prokaryotic
