En una carrera ciclística como las de Tour de Francia hay etapas en las cuales los ciclistas deben pedalear durante largos recorridos por montañas muy empinadas o por zonas planas donde se alcanza una mayor velocidad, a lo largo de la jornada los ciclistas se alimentan constantemente. Cuando la carrera es muy prolongada los ciclistas deben disponer de la energía necesaria para que sus músculos puedan responder adecuadamente durante toda la etapa, ¿cuál de los siguientes nutrientes debe ingerir en mayor cantidad un deportista para realizar una actividad como la descrita? Carbohidratos simples. Carbohidratos complejos. Grasas saturadas. Grasas insaturadas *

Ithink all of these events

Oh dog

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
