Summary

This document provides a summary of anaerobic respiration, discussing its biochemical pathways, roles in different organisms (like yeast), and its significance. It explains the processes of glycolysis and different types of fermentation such as lactic acid fermentation, while also mentioning the importance in diverse environments and applications in food production, energy generation, and muscle function.

N N AA EE RR O O BB I AA RREESSPPIIRRAATTIIOONN ICC OBJECTIVES To Understand the Biochemical Pathways of Anaerobic Respiration To Compare Anaerobic and Aerobic Respiration To Discuss the Biological Significance of Anaerobic Respiration CELLULAR RESPIRATION CELLULAR RESPIRATION IS THE PRODUCTION OF ATP, WHICH CELLS USE FOR ENERGY. IT OCCURS IN THREE MAIN STAGES: GLYCOLYSIS KREBS CYCLE ELECTRON TRANSPORT CHAIN ANAEROBIC RESPIRATION Chemical breakdown of glucose in the absence of oxygen Occurs in the cytoplasm of cell Organisms have capacity to carry out anaerobic respiration under conditions when oxygen is not available (lack of oxygen for short periods or permanently). This ability enables organisms to continue functioning under these conditions or to live in habitats where oxygen is absent glycolysis (in both aerobic & anaerobic respiration) Glycolysis plays a crucial role in anaerobic respiration by breaking down glucose into pyruvate, generating a small amount of ATP (energy) in the absence of oxygen. fermentation Fermentation is a specific type of anaerobic respiration that occurs after glycolysis, allowing for the regeneration of NAD+. This is essential for glycolysis to continue. There are several types of fermentation. Two of these types are lactic acid fermentation and alcoholic fermentation. Lactate dehydrogenase – is an enzyme required during the process of turning sugar into energy for our cells lactic acid fermentation LACTIC ACID FERMENTATION is a metabolic process that helps in a metabolic process that helps in generating NAD+ for glycolysis to continue; the product is lactate or lactic acid lactic acid fermentation Lactic acid is produced during anaerobic respiration. This happens when there is not enough oxygen for normal aerobic respiration to take place. Lactic acid is a mild toxin. It is responsible for the pain you feel in your muscles when they get tired. Muscle Function SPRINTING WEIGHTLIFTING Food Production YOGURT KIMCHI Alcoholic Fermentation Alcoholic Fermentation It is a type of anaerobic respiration in which glucose is converted into ethanol (alcohol) and carbon dioxide in the absence of oxygen. This process allows organisms, such as yeast and some bacteria, to produce energy when oxygen is not available for aerobic respiration. Importance of Anaerobic Respiration 1. Energy without oxygen 2.
