Abstract
In this paper I will describe photosynthesis, aerobic respiration, fermentation, and
enzymes. I will discuss how energy is transferred; the role of fermentation plays in allowing
organisms to generate energy without the use of oxygen and how an enzyme catalyzes a reaction.
Explanations on photosynthesis and respiration being linked in order to provide energy from the
food we eat. Also explanations of oxygen in some cells with the absence of oxygen can use
fermentation to produce energy from sugar created by photosynthesis. There are reactions that
occur under conditions that sustain life and cells uses these enzymes as biological catalysts to
increase the rate of reactions.
Photosynthesis is a metabolic process in which inorganic material is turned into
the organic material with the help of sunlight and with use of atmospheric carbon
dioxide, or the process by which solar energy is trapped and stored as chemical
energy in the bonds or organic molecules such as sugar. Photosynthesis gives out
oxygen as a byproduct. (Audesirk, Audesirk, & Byers, 2011) Respiration in
animals uses oxygen produced from the atmosphere produced by plants to
generate energy in the metabolic process undergoing several stages. Respiration
uses oxygen and gives back the carbon dioxide and therefore forms the raw
materials for the plants to utilize again.
Photosynthesis and aerobic respiration are essential processes that occur at the
cellular level in living organisms. Photosynthesis is the process in which plants
produce food and/or energy to support growth. During the aerobic respiration
process, plants burn the food products of photosynthesis in order to transform it
into usable energy. Both plants and animals survive off aerobic respiration but
animals do not participate in the process of photosynthesis. (Wahlig, 2010) In
animals, glucose is ingested through external food sources rather than produced
internally through photosynthesis. Aerobic respiration and photosynthesis both
produce a usable form of energy called ATP (adenosine-triphosphate). The
molecules that provide the raw ingredients for photosynthesis, water and carbon
dioxide enters at different stages of the process and are used in different parts of
the chloroplast. Oxygen is liberated by the photosynthesis and is derived from
water while the carbon used in the synthesis of sugar is obtained from carbon
dioxide. (Audesirk, et al, 2011)
In order for energy to be transferred within cells to produce usable energy in the
form of ATP, the cell must use an electron transfer compound. This function is to
accept the electrons from one compound into another the process of oxidization.
