The RNA synthesis or ADN transcription occurs in the nucleus and requires:
- DNA strand to act as a template.
- Enzymes, specially the RNA-polymerase.
- Ribonucleotides of Adenine, Guanine, Cytosine and Uracil.
This consist of three maturation of the 3'-->5' direction while the sense of RNA synthesis is 5'-->3'.
This is fulfilled because the enzyme selects the ribonucleotide whose base is complementary to the DNA chain that acts as a template, and binds it by means of a nucleotide bond, releasing a phosphate group.
Muscle glycogen is the primary fuel used during endurance exercise. Catabolism and anabolism are the two phases of metabolism.
Answer:
Energy released by the electron transport chain is used to pump H+ into <em>the mitochondrial intermembrane space</em> - Option D-.
Explanation:
There exist three proteinic complexes immersed in the internal mitochondrial membrane. These complexes have the electron transporters and the enzymes necessary to catalyze the electron transference from one transporter to the other. In complexes, I and III released energy by electrons provokes changes in membrane transport protein conformation. These changes make possible the protons transport against their concentration gradient, going from the mitochondrial matrix toward the intermembrane space. The protons concentrations difference between the matrix and the intermembrane space represents released energy.
