Active transport could transport material across the membrane against the concentration gradient
When you spin around, you lose balance because of fluid spinning around in the C) semicircular canals.
The gravitational force is being felt as the Earth pulls the train downwards using the two forces. The coils that provide the forces releases an electrical current which makes an electromagnetic field. It repels the materials with an equal force that goes up as well.
Answer:
1. When you eat, you take in large molecules called "macromolecules" which make up building blocks that you can absorb into the bloodstream, and that your cells burn for energy.
2. Sugar molecules - Glucose, Amino Acids - Proteins, Fatty Acids - Fat
3 - 5 seems like answers you have to do yourself, but if you really need help just comment and I'll edit this!
Explanation:
The correct answer is the last statement.
If the regulatory serine is mutated to alanine, then acetyl-CoA carboxylase will get activated spontaneously and will produce malonyl-CoA. The increased concentrations of malonyl-CoA will obstruct the oxidation of fatty acids by preventing the entry of fatty acids into the mitochondria.
It is because the AMP-activated protein kinase phosphorylates the serine residues of acetyl-CoA carboxylase to inactivate it. If a mutation occurs in such residues, then the AMPL cannot phosphorylate acetyl-CoA carboxylase and this enzyme will get activated spontaneously.
In such a situation, there will be more than sufficient production of malonyl-CoA, which will inhibit the admittance of more fatty acid getting inside the mitochondria; this will indirectly prevent the oxidation of fatty acids.
