Questions

1. What is the name given to the types of organisms that can use photosynthesis to produce glucose? Self feeders know as Autotrophy is one type of organism that can use photosynthesis to produce glucose. They produce food for their own cells. In addition, provide THREE specific examples. Three types of organisms that can use photosynthesis to produce glucose are plants like ivy, algae, and animals.

2. What is the name given to the types of organisms that exclusively use aerobic cellular respiration to break down glucose to produce ATP for energy? In addition, provide THREE specific examples. Heterotrophy and Autotrophs are some of the types of organisms that exclusively use aerobic cellular respiration to break down the glucose to produce ATP for energy. If oxygen is lacking, how might cells meet their energy needs through fermentation? When oxygen is lacking and is not available for the reactions to take place in the body then the Glycolysis takes place. Some cells also ferment pyruvate to form lactic acid fermentation (Audesirk, Audesirk, and Byers, 2008) Explain and give some examples of cells that can do this. Microorganisms

3. Both photosynthesis and aerobic cellular respiration are examples of complex metabolic pathways, consisting of many linked chemical reactions that require enzymes to function. Briefly, explain two (ONLY TWO) attributes of enzymes in catalyzing chemical reactions and in metabolic pathways. Metabolic pathways interconverision of fats and proteins by immediate molecules that are formed along the pathways that breakdown glucose. Energy is provided by the breaking down of the substances. The molecules are synthesized when there is an excess of the intermediates (Audesirk, Audesirk, and Byers, 2008)
