breaks down glycosidic bonds within starch molecules. Transforming complex carbohydrates into simpler sugars
mitochondria
provides energy for the cell, site for aerobic respiration
Ribosomes
makes protein for the cell, and protein synthesis
cell membrane
controls what comes in and out of the cell
Cell wall
support and structure for the cell, helps maintain the shape
Cytoplasm
Jelly like substance where chemical reactions occur
vacuole
large sac in the middle of the cell which contains cell sap
Chloroplast
contains chlorophyll, where photosynthesis occurs
What happens to the active site when there is a reaction?
The active site will bind to the specific substrate to start the reaction
proteins
a large 3D molecule formed by a chain of amino acids. The 3D shape is formed by folding in the chain which depends on the sequence of amino acids
Factors that affect enzymes
Temperature being above the optimum, increase in pH and concentration
Magnification
The process of enlarging the physical appearance/image of something
Enzymes
Known as biological catalysts. Increases rate of reactions and speeds them up.
Magnification Equation
image size/actual size
Differences between light + electron microscope
electron has higher resolution + greater magnifaction so you can see a larger image and in more detail
Specialised cells
Cells that have a specific function. Around 200 in the human body, Adapted to their functions.
Fertilisation
Occurs in the oviducts of the female reproductive system. Cells in the lining of the oviduct transport egg cells (developing embryos) towards the uterus.
How are oviduct cells adapted?
hair like cilia which waves from side to side to sweep substances along
nucleus
controls the cell, contains DNA, genetic material and chromosomes
3 things a plant cell has which an animal cell doesnt
