"Cellular respiration is the process by which biological fuels are oxidised in the presence of an inorganic electron acceptor, such as oxygen, to drive the bulk production of adenosine triphosphate (ATP), which contains energy."
The process by which plants break down glucose and other organic compounds to release energy for cellular work.
Overview of Respiration: This topic covers an overview of respiration including its definition, types, and importance in plant physiology.
Stages of Respiration: This session introduces the different stages of respiration in plants such as glycolysis, the Krebs cycle, and the electron transport chain.
The Role of Oxygen in Respiration: This section covers the importance of oxygen in respiration, its source, and the oxygen consumption rate by plants.
Anaerobic Respiration: This teaches about the anaerobic respiration process in plants, its differences from aerobic respiration, and factors that trigger anaerobic respiration.
Respiration in Plant Cells: This lecture discusses the biochemical process of respiration in plant cells, including the different organelles involved and their functions.
Energy Production in Respiration: This topic explains how the process of respiration leads to the production of energy that plants use for growth and development.
Factors Affecting Respiration: This deals explicitly with variables that affect respiration in plants such as temperature, humidity, and light.
Regulation of Respiration: The concept of regulation in respiration covers how different factors control the rate of respiration in plants.
Photosynthesis Vs. Respiration: This covers the relationship between photosynthesis and respiration in plants, and how one process affects the other.
Aerobic vs. Anaerobic Exercise: This involves comparing the differences between aerobic and anaerobic exercise and their similarities with aerobic and anaerobic respiration.
Ethylene and Respiration: This study talks about ethylene's role in regulating respiration and senescence in plants.
Respiration and Postharvest Physiology: This lesson covers the importance of respiration in postharvest physiology, how to control respiratory rate, and strategies for extending shelf life.
Respiration in Different Plants: This topic emphasizes the differences in respiration in C3, C4 and CAM plants.
Aerobic respiration: This process occurs in the presence of oxygen, and it releases energy from glucose.
Anaerobic respiration: This respiration occurs without the use of oxygen. It occurs in some plants like waterlogged soils or submerged roots.
Photorespiration: This is a process that occurs in the light and involves the uptake of oxygen and release of carbon dioxide.
Dark respiration: This happens in the absence of light and involves the breakdown of carbohydrates like glucose to release energy.
Glycolysis: This is the initial stage of respiration where glucose is broken down into two molecules of pyruvate.
Citric acid cycle: This is the second stage of respiration where pyruvate is oxidized into CO2 to produce energy.
Electron transport chain: This is the final stage of aerobic respiration where electrons are transported down a sequence of carriers to produce ATP.
Fermentation: This process occurs in anaerobic conditions where glucose is converted into ethanol or lactic acid.
Pentose phosphate pathway respiration: This pathway produces NADPH and ATP through the breakdown of glucose-6-phosphate.
Nitrogen respiration: This involves the conversion of atmospheric nitrogen into a usable form by plants.
"Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from nutrients into ATP, and then release waste products."
"The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, producing large amounts of energy (ATP)."
"Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity."
"Although cellular respiration is technically a combustion reaction, it is an unusual one because of the slow, controlled release of energy from the series of reactions."
"Nutrients that are commonly used by animal and plant cells in respiration include sugar, amino acids and fatty acids."
"The most common oxidizing agent is molecular oxygen (O2)."
"The chemical energy stored in ATP (the bond of its third phosphate group to the rest of the molecule can be broken allowing more stable products to form, thereby releasing energy for use by the cell) can then be used to drive processes requiring energy, including biosynthesis, locomotion or transportation of molecules across cell membranes."
"The inorganic electron acceptor, such as oxygen, is necessary for oxidizing the biological fuels and driving the production of ATP."
