Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Explanation:
Answer: The energy flow takes place via food chain and food web. During the process of energy flow in the ecosystem, plants being the producers absorb sunlight with the help of the chloroplasts and a part of it is transformed into chemical energy n in the process of photosynthesis.

The pros of Adult Stem Cells is a fact among the widen range of diseases that can be treated with this therapy, Parkinson' s and Alzheiber' s diseases, didfferent types of cancer and their comordities, Diabetes Mellitus type 1, heart diseases , strokes, spinal cord and other neurological injuries , replace or repaired damaged organs, reduce the risk of developing a transplant rejection, among other can be included. Remember that only a qualified doctor can determined if a patient is a good candidate undergo a stream called therapy.
The cons of Adult Stem Cells is that using embryogenic stem cells is considered unacceptable by the laws of many countries and many religions. The difficulty of obtaining stem cells and the long period of growth required before use . It can cost prohobitive for many patients, unproven treatment often come with high rejection rates. Ethical controversy over use of stem cells from lab-fertilized human eggs.

Facilitated diffusion or facilitated transport is also known as passive-mediated transport is the movement of molecules or ions across a biological membrane through transmembrane integral proteins. This process does not require chemical energy from ATP as such molecules and ions use the movement of gradient concentration for diffusion.
