True: Growing and dividing cells need to use substrate to provide energy and materials for growth, maintenance and product formation. In immobilised (non-growing) systems the energy and materials are only required for cell maintenance and product formation

Preface The BIOTOL series of texts are designed to provide a self-study resource concerning the principles, practices and applications of biotechnology.
