What is the simple word equation representing the process of respiration?The word equation for respiration is: Food (Glucose) + Oxygen → Energy + Carbon dioxide.Why do plants respire?Plants respire to break down glucose and release energy, which is needed by every cell to perform life-sustaining activities.Define aerobic respiration.Aerobic respiration is the complete breakdown of glucose into carbon dioxide, water, and energy inside cells in the presence of oxygen.Define anaerobic respiration.Anaerobic respiration is the incomplete breakdown of glucose without the use of oxygen to produce ethyl alcohol, carbon dioxide, and energy.What are anaerobes?Anaerobes are organisms, such as yeast, certain bacteria, and parasitic flatworms, that can survive and obtain energy in the absence of oxygen.Why is yeast used in the making of wine and beer?Yeast is used to make wine and beer because it respires anaerobically to yield ethyl alcohol and carbon dioxide as end-products.What is the end-product of anaerobic respiration in animal muscle cells?The end-product of anaerobic respiration in animal muscle cells is lactic acid.What are the two major steps involved in aerobic respiration?The two major steps involved in aerobic respiration are breathing (the exchange of gases) and cellular respiration (the oxidation of food inside cells).How does breathing differ from cellular respiration regarding energy release?No energy is released during the mechanical process of breathing, whereas energy is released and stored as ATP during the biochemical process of cellular respiration.Why are we advised not to sleep under a tree at night?We are advised not to sleep under a tree at night because plants take in oxygen and give out carbon dioxide at night, which increases the concentration of carbon dioxide under the tree.How does gaseous exchange take place in plant leaves?Gaseous exchange in leaves takes place through tiny pores called stomata that open into air cavities.How do old woody stems facilitate gas exchange?Old woody stems facilitate gas exchange through specialized pores called lenticels that develop beneath the bark.How do root hairs obtain oxygen for respiration?Root hairs take up oxygen by extending into the air spaces present between soil particles.Why are photosynthesis and respiration considered opposite processes?They are opposite processes because photosynthesis synthesizes glucose and stores solar energy, whereas respiration breaks down glucose to release stored energy.Where do photosynthesis and aerobic respiration take place inside a plant cell?Photosynthesis takes place inside the chloroplasts, whereas aerobic respiration is completed inside the mitochondria of the cell.
