Study Notes
Respiration is a process that occurs in all living organisms, from single-celled organisms to multicellular organisms, to release energy needed for their survival. It can be divided into two types: aerobic and anaerobic respiration
- Aerobic Respiration: Aerobic respiration is the process of cellular respiration that uses oxygen to produce energy from glucose It is a continuous process that occurs inside the cells of animals and is common in most plants and animals, including humans The overall equation for aerobic cellular respiration is:
glucose (6 carbon) 6 carbon dioxide (6 carbon)
This process is divided into three stages: glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation During aerobic respiration, glucose reacts with oxygen, forming ATP that can be used by the cell, while carbon dioxide and water are created as byproducts
- Anaerobic Respiration: Anaerobic respiration is the process of cellular respiration that takes place in the absence of oxygen to produce energy It is common in lower plants and microorganisms, as it does not require oxygen Anaerobic respiration usually occurs in lower organisms such as bacteria and yeast, and in higher organisms during heavy activities The chemical equation for anaerobic respiration is:
glucose (6 carbon) 2 lactic acid (6 carbon)
During anaerobic respiration, glucose is broken down into lactic acid, which is then used to produce energy
-
Respiratory Organ: Respiration occurs in the cytosol and around the plasma membrane in prokaryotic cells, while in eukaryotic cells, respiration takes place in the mitochondria, which is also considered as the powerhouse of the cells The respiratory organs for the exchange of gases vary in different organisms. In humans, respiration occurs through the lungs, while in plants, it takes place through the stomata in the roots and the tiny pores in the stomata of the plant's skin
-
Aerobic and Anaerobic Respiration: Aerobic respiration is a process that requires oxygen, while anaerobic respiration does not Aerobic respiration is a continuous process that occurs inside the cells of animals and is common in most plants and animals, including humans Anaerobic respiration is a type of cellular respiration that takes place in the absence of oxygen
-
The importance of Respiration: Respiration is a process that is needed for the survival of all living organisms, as it is the process by which they release energy needed for their survival It is a set of metabolic reactions that take place in all living cells to release energy (ATP-Adenosine triphosphate) The breakdown of glucose in the plant cells is similar to that in other living beings
In the absence of oxygen, anaerobic respiration occurs, which is a type of cellular respiration that takes place in the absence of oxygen to produce energy This process is common in lower plants and microorganisms, as it does not require oxygen Anaerobic respiration usually occurs in lower organisms such as bacteria and yeast, and in higher organisms during heavy activities
In humans, during vigorous exercises, muscle cells undergo anaerobic respiration, where lactic acid is produced as the waste byproduct instead of carbon dioxide This process is disproven by the fact that our muscles, during vigorous exercises, undergo anaerobic respiration, where lactic acid is produced as the waste byproduct instead of carbon dioxide
In animals like cow, buffalo, dog, and cat, the respiratory organs and the process of breathing are similar to those in humans In earthworm, the exchange of gases occurs through the moist skin
In insects, respiration takes place through the tracheae, while in humans and other mammals, it occurs through the lungs In plants, the roots take in air present in the soil, and the stomata in the plant's skin exchange gases
Increased physical activity enhances the rate of breathing During inhalation, our lungs expand, and then come back to the originalstate as the air moves out during exhalation The respiratory organs for the exchange of gases vary in different organisms
