Summary - Biology for you

  • 1 life processes and cells

  • How do you call an animal cells wall ?

    blabla

  • 2 Humans as organisms

  • lol+lol=
    hihi
  • 3 Enzymes

  • How do you cal chemicals wich break down substrates?

    Enzymes

  • Enzymes come in two main types: Breakers and Builders

     

    Breakers break down things, like they brake down starch into sugar.

    Builders Build up small molecules into bigger molecules. 

     

    Enzymes have an active site, that is the part where it breaks down the substrates.

  • How is the chemical called wich speed up reactions?

    Catalysts

  • WHat is the Carbohydrase in our Saliva called?

    Amylase

  • An enzyme is ... because it can only control one kind of reaction

    Specific

  • How is it called if an enzyme 'died'

    denatured

  • ... means how Acid or alkali the substance is (where the enzyme works in)

    pH

  • 3.1 your nervous system

  • What does your Central Nervous System consist of?
    The brain and the spinal cord
  • What connects the Central Nervous System to different parts of your body?
    Nerves
  • What do nerves consist of?
    Nerve cells or neurones
  • Sense organs are our receptors. They send messages to the Central Nervous System telling it what has happened. These messages are sent along sensory neurones.
  • Muscles and glands are our effectors. The Central Nervous System sends messages telling them what to do. These messages are sent along motor neurones.
  • 3.2 neurones

  • How are the messages that nerves carry called?
    nerve impulses
  • Some axons have a fatty sheath around them.
  • In multiple sclerosis the fatty sheath breaks down.
  • 3.3 Synapses

  • How do you call the gap between two neurones?
    A synapse
  • Synapses have 2 other functions. They act as :
    -A resistor
    -A junction box
  • What are our synapses easily affected by?
    Drugs
  • What affects the neurones that join with muscles?
    Motor Neurone Disease

Summary - biology for you

  • 1 plants and organisms

    1. what is respiration?
    1. respiration is the release of energy from glucose in living cells.
  • energy is used up by:

    -working your muscles

    -transporing chemicals

    -active transport

    -constant temperature

     

  • what is aerobic respiration?

    • the release of a relatively large amount of energy in cells by the breakdown of food substances in the pressure of oxygen.
  • what is lactic acid

    lactic acid is is a by product without using oxygen

  • what is Anerobic respiration?

    release of a small amount of energy by the breakdown of food substances of oxygen

  • what is sexual reproduction

    the fusion of gametes to produce offspring genetically different from their parents

    ADVANTAGES:                                                                   DISADVANTAGES:

    only one parent required                                                    requires second partner

    large number of organisms produced in short time               finding a mate takes time/energy

    survive wel in conditions which parent grows                       sexual reproduction takes longer to produce offspring

     

  • what is asexual reproduction

    the production of genetically identical offspring to their parents

    ADVANTAGES                                                                      DISADVANTAGES

    •                                                                                                                                                                 combines genetic info from two parents                           lack of variation              
    • species may have greater chance of survival                    suited to move away ans live in different environments
  • 2 H2!!

  • Op welke kenmerken zijn rijken gebaseerd
    1 Eukaryoot of Prokaryoot
    2 Celwand
    3 Aantal cellen
    4 Voedings wijze
  • Wat is het verschil tussen eukaryoot en prokaryoot
    eukaryoot heeft een celkern en prokaryoot niet
  • wat zijn de verschillende voedingswijze
    Autrotroof (bv fotosynthese)
    Heterotroof (ander nodig voor voeding)
  • wat is het verschil in organische en anorganische stoffen
    organische stoffen zijn afkomstig van organismen of producten van organismen (bv eiwit)
    Anorgansiche stoffen komen zowel in organismen als in de lenloze natuur voor (bv water)
  • waar worden rijken in verdeeld
    stammen
  • waar worden stammen in verdeeld
    klassen
  • waar worden klassen in verdeeld
    orden
  • waar worden orden in verdeeld
    families
  • waar worden families in gedeeld
    geslachten
  • waar worden geslachten in verdeeld
    soorten
  • hoe heten deze indelingsgroepen op verschillende niveaus
    taxa (enkelvoud taxon)
  • waneer behoren organismen tot dezelfde soort
    waneer ze vruvchtbare nakomelingen kunnen voortbrengen
  • wat is een populatie
    een groep individuen van dezelfde soort in een bepaald gebied die samen een voortplantingsgemeesnschap vormen
  • wie heeft binaire naam geving bedacht
    zweedse bioloog Linnaeus
  • hoe werkt de binaire naamgeving
    iedere soort krijgt een geslachtsnaam een een soortaanduiding
  • Waar bestaat het erfelijk materiaal uit bij veel soorten bacterien
    één kringvormige chromosoon
  • hoe planten bacterien zich voornamelijk voor
    door deling
