Answer:
c) repeat the cell cycle continuously
Explanation:
Cell division is a normal phenomenon for all cells as this is the way the cell reproduces and gets repaired in living organisms. However, some cells, due to mutation, keeps dividing and proliferating to form tumours. These cells are called CANCER cells. A normal cell undergoes cellular repair at certain checkpoints of the cell cycle. The checkpoints are necessary to determine a faulty cell and stop its division.
However, cancerous cells do not undergo any repair, which is why they do not enter the G0 phase as mentioned in the question. They keep on dividing out of control without death by repeating the cell cycle continuously.

Answer:
El adenosín trifosfato (ATP), es la moneda energética de los seres vivos. Para poder ser sintetizado, los organismos requieren oxidar los sustratos energéticos de la dieta, proteínas, grasas y carbohidratos. Inicialmente estas sustancias tienen vías metabólicas separadas hasta alcanzar en su degradación un metabolito común que es el acetil CoA. A partir de este punto en el ciclo de Krebs, con producción de CO 2 e hidrogeniones, estos últimos se transportan por reducción de óxido a la cadena respiratoria donde se formará agua endógena y ATP. Para lograr esta oxidación de los sustratos con alta producción de energía, es indispensable el oxígeno que actúa como comburente en las reacciones.
