Answer:
The correct answer is: catalysts lower the activation energy of the reaction.
Explanation:
Catalysts are substances that in our bodies are commonly represented by enzymes (specialized proteins) and that are used in chemical reactions to speed them up.
In order to achieve this, catalysts lower the activation energy of chemical reactions, which is a value of energy that must be obtained for the reaction to actually happen.
Catalysts are constantly used in our bodies and are responsible for the proper functioning of every organ. These catalysts can be used over and over again because they are not consumed in the reaction.
This question seems like its too easy so i might have got it wrong.. but would't you just subtract 20 and 10 from 800 to get 770?
ummm I'm so sorry but I don't know the answer to this one. maybe try looking it up? I'm sorry again.
Answer:The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass. In a physical change, a substance's physical properties may change, but its chemical makeup does not.
Explanation:
Answer:
Mesophyll and bundle sheath cell.
Explanation:
C4 pathway is also known as hatch slack pathway it is a photosynthetic process in some plants. In this pathway carbon is extracting from carbon dioxide to able to use in sugar and other biomolecules. C4 is known as four carbon molecules which is the 1st product of this type of carbon fixation.
In this pathway rubisco enzyme works in the environment where lots of carbon dioxide and very little oxygen present. CO2 is transferred via malate or aspartate from mesophyll cells to bundle sheath cells. In bundle sheath cell CO2 is released by malate decarboxylation.
C4 plants use PEP carboxylase to absorb more amount of CO2 in the mesophyll cells. Phosphophenolpyruvate (PEP) which is 3 carbon molecule binds with CO2 and make oxaloacetic acid, it forms than malate, 4carbon molecule. Malate enters through a plasmodesmata into bundle sheath cell and release the CO2.
