Answer:
Explanation:
The main goal of metabolism is for the ultimate release of energy. Energy is simply a function of the ability to do work. In this context, we consider energy in one of it forms, chemical energy.
The chemical energy obtained through digestion of food mostly in the form of glucose is the fuel for almost all of life's processes. This chemical form of energy serves as the power house for our functioning.
Energy is required by the brain to power it and carry out its function. Without energy being supplied to the brain, there won't be a living being.
Energy is needed for locomotion and other life activities. The muscles, bones and other appendages gets their coordination power from the energy released during metabolic processes.
It can be said that all life activities revolves round how organisms obtains and utilize energy.
Nutrients are the nourishment we derive from feeding. The nutrients helps to build our body parts e.g proteins. Energy are derieved from carbohydrates. Fats and oil are also energy sources and they help life functions. Vitamins and minerals supplies needed materials to make everyday life activities successful.
Because it is catalyst which speeds up or slows down the speed of the chemical reaction without being changed or used up
Answer:
The correct answer is D. On the plasma membrane.
Explanation:
Prokaryotes do not have mitochondria to synthesize ATP but ATP synthesis takes place in prokaryotes on the plasma membrane as the plasma membrane contains the enzymes that are required for ATP synthesis.
The process of ATP synthesis is just like in the mitochondria. NADH helps in building the proton gradient in the outer portion of the membrane by the help of electron carriers embedded in the plasma membrane. Then these protons come back in the cytoplasm through ATP synthase enzyme complex.
This entry of protons helps in the generation of ATP from ADP and inorganic phosphate with the help of ATP synthase enzyme. Therefore the correct answer is D. On the plasma membrane.
The answer is approximately 42.57 kDa. The average weight of an amino acid is 110 Daltons. Therefore, a generic amino acid of 387 amino acids will have 110 *387 = 42570 Daltons. 1000 Daltons is equal to 1 kDal. Therefore 42570/1000 = 42.57 kDa
