Cell
-
-
-
-
Simplest organism = made from a single cell
Complex plants and Animal cells = are composed of millions of cell
Respiration process
-
-
-
happens in the cells of human and those if animals, plants and many other organism.
-
-
-
-
Ethanol makes a good fuel and will burn to produce a lot of heat, so it still has a lot of chemical energy
-
If muscle overworked, the blood cannot reach them fast enough to deliver
-
-
-
-
Oxygen debt =oxygen needed to comple oxidise the lactate that builds up in the body during anaerobic
-
Enzyme
-
-
-
-
-
human body without catalyzing reaction = 37
most reactions that happen in cells would be far to allow life to go on. The reaction can only take place quickly enough when enzymes are present to speed them up
-
HOW CELL GETS ITS ENERGY
cell gets energy by breaking down food molecules to release the stored chemical energy that they contain. This process is called respiration
-
Oxygen is used to oxidise food, and carbon dioxide (and water) they are release as waste product
-
-
-
- Contraction of muscle cell, producing movement
- Active transport of molecules and ions
- Building large molecules, such as proteins
- Cell division
-
Cell Membrane
-
-
"Skin" on the surface forms a boundary between the cytoplasm of the cell and the outside. However it's not a complete barrier
-
-
-
Cell Wall
-
-
Cellulose tough material that helps the cell to keep it shape and reason why "body" of a plant has a fixed shape
-
The cell wall is porous so it's not a barrier to water or dissolved substances called freely permeable
Cytoplasm
-
The texture rather like sloppy jelly, between solid and a liquid. Unlike a jelly it's not made from one structure but it's made from complex material made of many different structures
Electron Microscope has higher magnification that can show detail of the structure which are called organelles
-
Chroloplast
-
-
Cell from part of plant that is not green such as flower, roots and woody stems have no chloroplast
Vacuole
-
-
Animal cells do contain vacuoles, but they are only small, temporary structures
-
