Number One<\/td>\n

Metabolic Pathways<\/p>\n

 <\/p>\n

We are on page 5 of our notes!<\/p>\n

Metabolism is the sum of all chemical reactions within an organism.<\/p>\n

Put simply, energy allows things to move.<\/p>\n

Energy can be stored or used by the body.<\/p>\n

Key players in the metabolic game of energy are ATP, Oxygen, ATP, Vitamins, Calcium and yes..Enzymes.<\/p>\n

 <\/p>\n

A cell can move, grow and reproduce. In each case you need energy.<\/p>\n

 <\/p>\n

Energy can be potential or kinetic<\/p>\n

 <\/p>\n

Potential is stored energy<\/p>\n

Kinetic energy is linked to breaking down stored energy<\/p>\n

 <\/p>\n

Key terms: Anabolic (make) and Catabolic (break)<\/p>\n

 <\/p>\n

So simplify: I ate cereal and now I have energy.<\/p>\n

a)\u00a0\u00a0 Glycolysis is the break down of sugar.<\/p>\n

b)\u00a0\u00a0 By breaking down sugar, the body can convert products into ATP.<\/p>\n

c)\u00a0\u00a0\u00a0 By adding Hydrogen to Oxygen, the body has an efficient way to make ATP<\/p>\n

 <\/p>\n

To move you need energy, so does a cell.<\/p>\n

In order, energy demands can be met by breaking down<\/p>\n

a)\u00a0\u00a0 complex sugars to monosaccride, then to atp<\/p>\n

b)\u00a0\u00a0 complex fats broken down to fatty acids can merge with sugar being metabolized.<\/p>\n

c)\u00a0\u00a0\u00a0 Complex proteins can be broken down and added to sugar metabolic pathway.<\/p>\n

 <\/p>\n

To break things down, you need energy.<\/p>\n

You do not want to use more energy to break things down, than what you will get from catabolic pathways..<\/p>\n

So we need enzymes!<\/p>\n

Topic<\/p>\n

Number Two<\/td>\n

First of all a shout out for enzymes..<\/p>\n

Bozeman Science<\/p>\n

https:\/\/www.youtube.com\/watch?v=ok9esggzN18<\/a><\/p>\n

 <\/p>\n

So how can we observe an enzyme reaction?<\/p>\n

 <\/p>\n

Note: Substrate plus enzyme will make product<\/p>\n

 <\/p>\n

If you change the amount of substrate, you need more enzyme.<\/p>\n

 <\/p>\n

If you have a functional enzyme it will make a product.<\/p>\n

You can measure a variety of enzyme reactions by identifying the product.<\/p>\n

 <\/p>\n

Some easy enzyme reactions to monitor are:<\/p>\n

 <\/p>\n

Amylase reaction<\/p>\n

http:\/\/intro.bio.umb.edu\/OLLM\/111F98\/pdfs\/Amylase.pdf<\/a><\/p>\n

 <\/p>\n

Starch is a poly saccharide to break it down you can make into a disaccharide. What is the difference between amylase and maltase?<\/p>\n

 <\/p>\n

A story on amylase<\/p>\n

https:\/\/www.youtube.com\/watch?v=HTJy3lnPmL8<\/a><\/p>\n

 <\/p>\n

Catalase Reaction<\/p>\n

https:\/\/www.scientificamerican.com\/article\/bring-science-home-liver-helping-enzymes\/<\/a><\/p>\n

 <\/p>\n

Peroxide (H2O2) bleaches your hair, cleans up a would but can affect your body. Catalase converts peroxide into water and oxygen!<\/p>\n

 <\/p>\n

Is there a metabolic relationship between amylase and catalase?<\/p>\n

 <\/td>\n

 <\/td>\n<\/tr>\n
Topic<\/p>\n

Number Three<\/td>\n

If you change the structure of an enzyme, you will decrease the amount of product.<\/p>\n

Some changes are permanent.<\/p>\n

Some changes do not change the structure of the enzyme.<\/p>\n
