Answer:
questions) *Differentiate between aerobic and anaerobic respiration.
answer The difference between aerobic and anaerobic respiration.
Aerobic respiration Anaerobic respiration
1. Aerobic respiration refers to complete breakdown of metabolic fuels in presence of oxygen.
1. Anaerobic respiration is the process of partial breakdown of fuel (glucose) in absence of oxygen.
2. It includes glycolysis, citric acid cycle and oxidative phosphorylation. The first two processes take place in the cytoplasm while last one occurs in mitochondria.
2. Glycolysis is followed by ethanol fermentation (occurs in yeast) or lactic acid fermentation (in muscles and microbes like lactic acid bacteria).
3. The end products are carbon dioxide and water.
3. End products of ethanol fermentation are ethanol and carbon dioxide; that of lactic acid fermentation are lactic acid
4. Owing to complete oxidation of glucose, a large amount of energy is produced (36-38 ATP molecules)
4. Incomplete oxidation of glucose does not release all stored energy and only 2 ATP molecules are produced.
questions 2) *Prove with an activity to show that microorganisms release carbon dioxide.
answer 2) As microbes in the soil break down fallen plant matter, a diet "balanced" in nutrients appears to help control soil fertility and the normal release of the greenhouse gas carbon dioxide into the atmosphere.
questions 3) *Explain how glucose is broken down.
answer 3) If oxygen is present, then glucose can be broken all the way down into carbon dioxide and water. This process is called aerobic respiration because it requires air (oxygen). In the absence of oxygen, the cell uses a process called anaerobic fermentation. or simply fermentation.
questions 4)*Define ATP.
answer 4) Adenosine triphosphate is an organic compound that provides energy to drive many processes in living cells, e.g. muscle contraction, nerve impulse propagation, and chemical synthesis. Found in all forms of life, ATP is often referred to as the "molecular unit of currency" of intracellular energy transfer.
questions 5) * Explain the process of respiration in plants.
answer 5) The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce their own food to survive
questions 6) * Explain how respiration takes place in aquatic animals.
answer 6) Through Gills
A majority of aquatic animals like fish and prawns breathe through special organs called gills. ... To get oxygen dissolved in water, fish gulp water through the mouth and pump it over the gills. Water passes into the gill chamber through gill slits. In each chamber, the water passes over the filaments.
questions 7) * Explain the process of respiration in humanbeings.
answer 7 ) Respiration is the process by which energy is released from food in our body. The function of respiratory system is to breathe in oxygen for respiration producing energy from food, and to breathe out carbon dioxide produced by respiration.With the help of lungs gases are exchanged between the blood and the air.
