- Biology
- features of all living things
- move - bacteria and animals move to find food, escape from predators, or find better conditions.
- Respire - energy is needed to carry out cell processes.
- Respiration is a series of chemical reactions that releases energy from food
- Sense - living things sense and respond to their surroundings . plants grow towards the sunlight, while woodlice's running away from the sunlight
- Excrete- living cells produce waste
- Waste is removed by excretion. and carbon dioxide is a waste product
- grow - bacteria grow and divide to form new bacteria. plants and animals are made from billions of cells.
- Feed - living things get a supply of energy from their food.
- plants makes their food from photosynthesis
- reproduce - all living things eventually die. reproduction makes new generations.
- enzymes are Catalyst that speeds up a reaction, but it doesnt get used up .
- the lock - and -key model explains how enzymes work
- only the right shape molecule fits into the enzymes active site
- without enzymes at 37*c enzymes chemical reactions in your body would happen too slowly to keep you alive.
- a higher body temperature speeds up the chemical reactions in your body
- higher temperatures damage human cells. we need enzymes to live.
- for a higher body temperature you would need a lot more food to fuel respiration
- higher temperatures damage human cells. we need enzymes to live.
