Study Notes
Respiration
- Pyruvic acid is converted into carbon dioxide, releasing energy and forming water molecules at the end of this process.
- In anaerobic respiration, pyruvic acid is converted into ethyl alcohol or lactic acid in the absence of oxygen.
Aerobic and Anaerobic Respiration
- Aerobic respiration occurs in the presence of oxygen, producing carbon dioxide, water, and energy.
- Anaerobic respiration occurs in the absence of oxygen, producing either ethyl alcohol or lactic acid.
Respiration in Muscles
- During intense physical activity, anaerobic respiration occurs in muscles, forming lactic acid and causing pain.
- The pain subsides after rest, as lactic acid is removed and oxygen is replenished.
Large Intestine
- The large intestine is smaller than the small intestine.
- Undigested food enters the large intestine, where water and salt are absorbed, and the remaining waste is expelled through the anus.
Respiration in General
- Respiration is the process by which living beings utilize food to produce energy.
- It is an oxidation reaction that occurs in mitochondria, releasing energy stored in ATP (adenosine triphosphate).
- The steps of respiration include breaking down glucose into pyruvate, and further breaking down pyruvic acid into different molecules depending on the type of respiration.
Photosynthesis
- Photosynthesis occurs in the presence of sunlight, chlorophyll, CO2, and water.
- The process involves absorption of light energy, conversion into chemical energy, and splitting of water molecules.
- CO2 is reduced to carbohydrates, releasing oxygen as a byproduct.
Stomata
- Stomata are tiny pores in the epidermis of leaves and stems that facilitate gaseous exchange and transpiration.
- Functions of stomata include exchange of gases (O2 and CO2) and transpiration, losing water vapor.
