,• Bioenergetics – the field of biochemistry
concerned with the transfer and use of energy
by biological system
• BIOLOGICAL IMPORTANCE:
• Suitable fuel is required to provide the energy
that enables the animal to carry out its normal
processes
• How the organism obtains this energy from its
food is basic to the understanding of normal
nutrition and metabolism
,• Death from starvation occurs when available
energy reserves are depleted, and certain forms
of malnutrition are associated with energy
imbalance (kwashiorkor, marasmus)
• Storage of surplus energy results in obesity
• Of key importance in bioenergetics is the
application of basic principles of
thermodynamics (branch of physical science that
deals with energy transformations) to the study
of energy transformations within cells
, • Energy – is a highly abstract concept,
which is best understood and measured
by its effects
• Energy is defined as the capacity to do
work, and it is denoted by the symbol E
• It can manifest itself in different forms such
as mechanical, thermal, chemical,
electrical or radiant energy
