Sometimes animals and plants cannot get enough oxygen to respire aerobically, such as during intense exercise, but they still need to respire to survive. After all, everything relies on respiration for energy. Luckily there is a back-up plan; anaerobic respiration. The generalised equation for anaerobic respiration in muscles is: glucose --- lactic acid + energy. There is no oxygen involved in anaerobic respiration. It is much less efficient than aerobic respiration, and much less energy is released. This is because the glucose is only partially broken down. Another problem is that lactic acid is produced. This is actually a poisonous chemical that if it builds up in the body, the muscles stop working and you get muscle cramp.You can only get rid of the lactic acid by taking in oxygen again and thus replacing the oxygen debt. Oxygen is needed to break down the lactic acid, turning it into carbon dioxide and water. The oxygen supply can also run out for plants too, such as in waterlogged soils. This then forces plants to have to carry out anaerobic respiration, as they too need to respire constantly. The generalised anaerobic respiration equation for plants is: Glucose --- Ethanol + Carbon Dioxide + Energy. In yeast, this process is called fermentation and is used to bake bread and brew alcohol.

Interest is the amount charged by a lender to a borrower. It means that if you borrow some money from a bank, you have to pay back more than the money you borrowed. Equally, if you have a savings account and deposit some money, the bank will pay you interest as a sort of thank you for saving with th
In this video we are going to look at a few different ways in which plant hormones can be used. Plant growth hormones (auxins) can be used as selective weedkillers. The selective weedkillers contain growth hormones, that cause the weeds to grow really quickly. This means the weed is absorbing nutr
Algebraic fractions are simply fractions with algebraic expressions either on the top, bottom or both. We treat them in the same way as we would numerical fractions. In this video we look at how to simplify algebraic fractions, and how to add and subtract them. VISIT us at www.fuseschool.org, wh
