ARTICLE SUMMARY 3
Thearticle CellEnergy and Cell Functionsattempts to discuss where cells obtain their energy, how they turnnutrients into usable energy, the specific pathways that cells use,and how they keep energy in reserve.
Accordingto the article, it is difficult for cells to produce energy withoutthe presence of a source in the environment that they are in.Specialized plant cells usually utilize sunlight in producing energy.The sunlight tapped by the cells is usually used in making complexfood molecules, which exist in the form of sugars and fats. It isthese food molecules that provide energy for the cells. The articlerecords that the food molecules have to pass through the cellmembrane, when being passed to the cells (Nature Education, 2014).The article argues that scientists have the capacity of measuring theamount of energy stored in foods through the help of a bombcalorimeter. The food molecules generated by the cells are stored inthe cells and have to be oxidized so as to produce energy that isutilized by cells for the various processes (Nature Education, 2014).In addition, the article indicates that the type of cell isexceedingly critical in determining the energy pathway this impliesthat eukaryote and prokaryote have different energy pathways.According to the article, eukaryote cells usually use three chiefprocesses in its energy pathway.
Thearticle further argues that when the energy is in abundance,eukaryotes cells usually make larger, energy-rich molecules thatstore the excess energy. The resulting fats and sugars are then heldin reservoirs within the cells. According to the article, plant cellsmake starch that is stored in granules (Nature Education, 2014).
