Why can cells function so efficiently under anaerobic conditions? Please help.© BrainMass Inc. brainmass.com October 24, 2018, 6:50 pm ad1c9bdddf
Cells that can function under anaerobic conditions have enzymes that enable them to "ferment."
As you know, anaerobic means without oxygen. Oxygen is needed as the terminal electron acceptor in the electron transport chain at the inner mitochondrial membrane in order to allow the oxidative phosphorylation process to occur so that lots of ATP can be made from the reduced cofactors, NADH and FADH2.
Without oxygen, oxidative phosphorylation stops and no more ATP ...
The solution discusses why cells function so efficiently under anaerobic conditions.
Cellular Respiration, Photosynthesis and Enzyme Function
Cellular Respiration and Photosynthesis co-exist as paired metabolic processes.
Photosynthesis uses light energy to convert carbon dioxide into glucose, a simple sugar, in two steps, the light dependent and light independent reactions. Oxygen is produced as a by product during photosynthesis. This reaction stores energy in the chemical bonds of glucose.
Sugar and other carbohydrates are used as fuel sources by cells. During the process of Aerobic Cellular Respiration, glucose is broken down using oxygen. This reaction releases energy which is used to create ATP molecules, the energy carrier molecule of cells. The process also releases Carbon Dioxide as a byproduct.
Download and fill out the attached table to compare and contrast Photosynthesis and Aerobic Cellular Respiration.
After completing the table use the table, along with additional reference information, to answer the following questions.
1)What is the name given to the types of organisms that can use photosynthesis to produce glucose? In addition, provide THREE specific examples.
2)Would cyanide affect bacteria that use anaerobic respiration? To answer this you will need to consider the role of oxygen in aerobic cellular respiration. Explain your answer.
3)If oxygen is lacking, how might cells meet their energy needs through fermentation? Explain and give some examples of cells that can do this.
4)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
