Liver and Enzyme Lab by Bryce Asby https://padlet.com/asbyb/rnsucag65z8f Honors Biology Bryce Asby en-us 2016-09-17 17:59:09 UTC 2025-10-05 07:27:47 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/File.png Problem asbyb https://padlet.com/asbyb/rnsucag65z8f/wish/124528627 How does the enzymes in liver react to water and peroxide?]]> 2016-09-17 18:04:44 UTC https://padlet.com/asbyb/rnsucag65z8f/wish/124528627 Hypothesis  asbyb https://padlet.com/asbyb/rnsucag65z8f/wish/124528692 The liver will have a reaction when peroxide is added but not when water is added ]]> 2016-09-17 18:06:02 UTC https://padlet.com/asbyb/rnsucag65z8f/wish/124528692 Materials needed asbyb https://padlet.com/asbyb/rnsucag65z8f/wish/124528736 Cow liver and boiled cow liver
water
peroxide
5 test tubes
matches
2-4 wood sticks ]]> 2016-09-17 18:07:01 UTC https://padlet.com/asbyb/rnsucag65z8f/wish/124528736 Test Tube 1 asbyb https://padlet.com/asbyb/rnsucag65z8f/wish/124528842 Add water to 2 cm mark
Put piece of liver in the water
NO REACTION]]> 2016-09-17 18:10:02 UTC https://padlet.com/asbyb/rnsucag65z8f/wish/124528842 Test Tube 2 asbyb https://padlet.com/asbyb/rnsucag65z8f/wish/124528870 Add peroxide to 2 cm mark 
Put piece of liver in the peroxide
THERE IS A BUBBLY REACTION
Is the peroxide being turned into water and oxygen??]]> 2016-09-17 18:10:57 UTC https://padlet.com/asbyb/rnsucag65z8f/wish/124528870 Test Tube 3 asbyb https://padlet.com/asbyb/rnsucag65z8f/wish/124528923 Add peroxide to 2 cm mark 
Light a wooden stick on fire 
When the fire is out but the end is still glowing red, stick the wood into the peroxide
NOTHING HAPPENS BECAUSE PEROXIDE IS NOT FLAMMABLE 

]]> 2016-09-17 18:12:20 UTC https://padlet.com/asbyb/rnsucag65z8f/wish/124528923 Test Tube 4 (will prove that pure oxygen is being produced) asbyb https://padlet.com/asbyb/rnsucag65z8f/wish/124528997 Add peroxide to 2 cm mark
Put piece of liver in the peroxide
THERE IS A BUBBLY REACTION (Like test tube 2)
Light another wooden stick on fire and do the same thing. When glowing red, place it in the peroxide. But this time, the stick will ignite again because oxygen is being given off by the peroxide.

Then add the boiled liver and make sue it is in the bottom
Add peroxide to 2 cm mark 
NOTHING HAPPENS BECAUSE NO OXYGEN IS BEING GIVEN OFF- Enzymes do not work because no bubbling of the peroxide]]> 2016-09-17 20:58:14 UTC https://padlet.com/asbyb/rnsucag65z8f/wish/124534337 What are enzymes? asbyb https://padlet.com/asbyb/rnsucag65z8f/wish/124534400 They increase the rate of chemical reaction in the cell by lowering the level of energy necessary to start the reaction ]]> 2016-09-17 21:00:31 UTC https://padlet.com/asbyb/rnsucag65z8f/wish/124534400 The effect of temperature on Test Tube 5 asbyb https://padlet.com/asbyb/rnsucag65z8f/wish/124534545 The extreme temperature of the boiling liver is why there is no oxygen being given off]]> 2016-09-17 21:08:07 UTC https://padlet.com/asbyb/rnsucag65z8f/wish/124534545 Conclusion  asbyb https://padlet.com/asbyb/rnsucag65z8f/wish/124534592 My hypothesis was correct because the liver did not react to the water but did to the hypothesis]]> 2016-09-17 21:10:03 UTC https://padlet.com/asbyb/rnsucag65z8f/wish/124534592
