What are the ditferent ways in which glucose is oxidised to provide energy in various organisms |
| Answer» Breaking down of glucose involves two processes. In the first step, it is broken into three carbon molecules called pyruvate. The pyruvate is further broken down into energy in following different ways in various organisms.1) Aerobic respiration : In this case pyruvate is broken down into water and carbon dioxide along with release of energy. It commonly occurs in mitochondria of cells.2) Anaerobic respiration in yeast : In yeast cells during fermentation pyruvate is converted into ethanol and C02 in the absence of 02.3) Anaeorbic respiration in muscles: Due to lack of oxygen, eg. during vigorous running or exercise, in human muscles, pyruvate is converted to lactic acid. | |

How are air sac designed to maximise the exchange of gases |
|
Answer» Air sac are generally called alveoli . Alvioli are richly provided with blood capillaries . The walls of these air sac are moistened which help in easy exchange of gases . As the blood circulates throughout the body and bring CO2 from the different body parts in alveoli CO2 diffuses in alveoli and it is exhaled . After exhaling it O2 is inhaled which enters capillaries by process of diffusion. In this way alveoli provide a much larger surface area for exchange of gases . Alveoli is ballon like structure which are connected by many blood cappillaries and when we inhale oxygen the size alveoli increase and diffuse to blood cappillaries . After it diffuse co2 gas which exhale out. Note that alveoli have much larger surface area in body. with the help of alvieoli |
