por que podemos afirmar que a respiraçao aerobia é energeticamente mais eficiente que o processo de fermentação ?
denis-greek [22]
A fermentação é um processo de transformação de uma substância em outra, produzida a partir de microorganismos, tais como fungos, bactérias, ou até o próprio corpo, chamados nestes casos de fermentos.
Existem 2 tipos de fermentação: A fermentação láctica e alcoólica. Este tipo de obtenção de energia não necessita do oxigênio como aceptor final de elétrons, por isso é chamado de respiração anaeróbica. Ambos os tipos de fermentações produzem 2 ATP no final do processo por molécula de glicose.

Portanto, o processo fermentativo apresenta um rendimento energético bem inferior ao da respiração aeróbica.
