<u>Answer;</u>
C) organic matter; rocks.
The uppermost horizon, horizon O, in this profile is composed mostly of <u>organic matter</u>, while the lower horizon, horizon C, is composed mostly of <u>rocks.</u>
<u>Explanation;</u>
-Soil contains the following major horizons, that is A B and C. Some soils may have horizon O, which may be thin or thick or even lack in some soils. This O horizon is found at the surface of many soils and normally contains organic materials at various decomposition stages. these are materials such as plants, leaves and bugs.
-C horizon is the layer that is below the B horizon. It contains larger weathered fragments or broken up-bedrock.
Cytoplasm. This photo should help explain it!
The option which would most likely result in the greatest decrease in the rate of a chemical reaction is adding an enzyme inhibitor to a reaction catalyzed by an enzyme.
Enzyme inhibitor is known for slowing down any processes, especially when it comes to chemical reactions, so I'd say A is the correct answer.
Answer:
If 10 glucose molecules are broken down, 320 ATP molecules will be generated during the electron transport chain.
Explanation:
In the electron transport chain, high energy electrons travel across a series of proteins embedded in the inner mitochondrial membrane, releasing energy in the process.Hydrogen is pumped from the matrix into the intermembrane space, therefore an hydrogen ion gradient is formed across the inner membrane.These proton are then pumped back into the mitochondrial membrane where the synthesis of ATP from ATP synthase takes place.
In the electron transport chain, a total of 32 ATPs are generated per glucose molecule.
so if 10 glucose molecules are broken down:
1 glucose ⇒ 32 ATPs
10 glucose ⇒ 10*32
320 ATP molecules
Eukaryotic cells have a membrane-bound nucleus, whereas prokaryotic cells do not. In eukaryotes, the nucleus is just one of numerous membrane-bound organelles. Prokaryotes, on the other hand, lack organelles that are attached to the membrane.
