Respiration is the chemical process that supplies the body with energy for all other life processes: growth and repair of cells, muscle contraction, protein synthesis, sending nerve impulses, absorbing molecules in active transport to name just a few. It happens in ALL living cells, not just animal cells but also plant cells. There are two types of respiration: aerobic and anaerobic respiration. Aerobic means “with air” and so needs oxygen, whereas anaerobic respiration doesn’t need oxygen. Aerobic respiration releases energy in cells by breaking down food substances whilst in the presence of oxygen. It is represented by this simplified equation Glucose + Oxygen ----- Carbon Dioxide + Water + Energy. Glucose is broken down by oxygen to release the by-products of carbon dioxide and water. Energy is released, which is then used to make a special energy molecule called ATP. ATP is how energy is stored for later use by the body. Aerobic respiration happens all the time in all cells, usually in the mitochondria. Click here to see more videos: https://alugha.com/FuseSchool

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
