Energy it is the ability to do work. Energy cannot be destroyed but it can be changed to another form. Without energy we would not be able to growth or move. To stay alive we need regular and permanent supply of energy or else we would die. Without energy our body would not be able to carry out processes such as: * Growth and reconstructions of new cells and tissues as energy is necessary to supply biochemical reaction that then is building larger organic molecules from simpler ones. * Active transport without energy wouldn’t be successful as energy is needed for moving the substances in and out of the cells e.g. by active transport amino acid is being delivered to the blood from the small intestine. * Movement as energy is necessary for all movements and human movements are occurring in certain stages: * Inside cells - chromosomes separating. * Whole cells – sperm swimming (to reach the egg sperm need to swim 7500 times its own length to reach the egg and without energy it would be impossible to do) * Tissues – muscles control * Whole organs – heart beating * Parts of whole organisms such as walking and talking.
Also we need the energy from respiration to maintain our body at a constant 37C as we human are warm blooded which can advantage or disadvantage us. Being warm blooded can disadvantage as warm-blooded bodies are providing nice and warm environment for viruses, bacteria’s and parasites to live in. The advantage of being warm blooded is that we can move then it is cold, as if we were cold blooded we wouldn’t be able to move during the cold weather.
As much as we need energy we also need food to keep us alive for humans food is like fuel and without it we
