Resource summary
Biology B4
Enzymes
Proteins produced by living things and speed up chemical reactions
require the correct conditions
Temperature
Higher will speed up the reaction until it gets too hot
changes shape of the substrate so it doesn't fit in to the active site - it's been denatured
PH Level
Interferes with the bonds holding the enzyme together. Changes the shape - Denatured
Cells
Similarities
Nucleus - contains DNA (instructions for protein)
Cyptoplasm - enzymes are made
Cell Membrane - controls what goes in and out
Mitochondria - Aerobic respiration takes place
Differences - What Plant cells have
Cell wall
Vacuole
Chloroplasts
Bacteria (Simple Cell Structure)
NO Nucleus - DNA Floats around in the cyptoplasm
No mitochonrdia
can still respire
Respiration
Aerobic Respiration
releases more glucose per molecule than ->
Most common
Anaerobic Respiration
Annotations:
NO OXYGEN
when you do a lot of exercise, muscles don't have enough Oxygen
Produces Lactic Acid
can produce Ethanol
Photosynthesis
6CO2 + 6H20 --> C6H1206 + 602
plants use glucose
1) Respiration 2) Make Chemicals for Growth 3) Stored as starch
3 factors that effect it are
Light intensity
amount of CO2
Temperature
Diffusion, Osmosis & Active Transport
movement of particles from a high concentration to a low
movement of water from a dilute to a more concentrated solution through a partially permeable membrane
movement of chemicals over a cell membrane from a lower concentration to a higher concentration
