Resumo de Recurso
Year 10 Edexcel Biology Exam
Topic 1: Key concepts
Cells
Can Be Prokaryote Or Eukaryote
Prokaryotes are simple
Eukaryotes are Complex
Plant and Animal Cells
Both Contain
Nucleus: 'brain of the cell'
Cytoplasm: where chem reactions occur
Cell membrane: controls what goes in and out
Mitochondria: Respiratiion
Ribosomes: translation
But plant Cells Contain
Cell Wall: supports cell
Vacuole: cell sap
Chloroplasts:photosythesis
Specialised Cells
Egg cells
haploid
sperm
tail for swimming
haploid
mitochondria
Ciliated Epithelial cells
cilia on top
Microscopy
See practical in Revision Guide (CGP) Page 14
Total magnification= eyepiece lens magnification x objective lens magnification
Magnification=Image size/real size
Enzymes
Are Catalysts
They Catalyise by either joining up or splitting apart the substarte
Enzymes have a active site specific to substrate
Tempreture, pH and substrate Conc affect rate of reaction
Check p.17
Rate=1000/time
Rate of Reaction
Enzymes Break Down Big molecules
Proteins, Lipids and Carbohydrates are examples
Protease Coverts Protein to amino Acids
Lipases covert Lipids to fatty acids
Amylase Converts Carbohydrates to simple sugars
You can test for sugars using Benedicts Reagent
Starch with iodiene
Emulsion Test For lipids
Energy in food (j)= mass of water x Temp x 4.2
Diffusion, Osmosis And Active Transport
Diffusion
movement of particles from High conc to low conc
Osmosis
movement of water through a partial permeable membrane from high to low conc
Active Transport
movement of particles from area of high conc to low conc against conc graidient using energy
