Respiration is an exergonic reaction. An exergonic reaction is one in
which energy is released, and as a result the products of this reaction
will have less energy than the original products. Cellular respiration
can also be referred to as a catabolic pathway, which means bigger
molecules get broken down into smaller molecules and therefore there is
extra energy at the end of the reaction.
Surface tension is caused by the attraction of the particles in the surface layer by the bulk of the liquid.
