Answer:
Energetic coupling of chemical processes in metabolic pathways Biochemical systems couple energetically unfavorable reactions with energetically favorable reactions. These reactions can be part of catabolic pathways where complex substances are broken into simpler ones with the release of energy or anabolic pathways where complex molecules are synthesized with an input of energy.
Explanation:
Answer:
C. Elongation.
Explanation:
The RNA strand "elongates" due to the addition of new nucleotides
Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.
Working with skeletal muscles, tendons, ligaments and joints, the bones form the moving machinery of human body. The major role of bones in movement is that they act as levers, which make use of the forces generated by skeletal muscles in a beneficial way.
