1. Daily Science
What do the circles #1-4 individually represent, monomers or polymers?
Answer: individual monomers
How do you store energy or make a polymer? By dehydration or hydrolysis?
Answer: Dehydration
Prepare to share research from yesterday!

2. Carbohydrates
Biology

3. Carbohydrates Carbohydrates are made of carbon, hydrogen, and oxygen.
Usually have a 1:2:1 ratio. (1 carbon: 2 hydrogen: 1 oxygen) CH2O
Carbohydrates are also known as sugars and starches.

4. Carbohydrates There are two types of sugar:
Simple – one or two monomers
Animals use simple sugars for immediate energy.
Plants make and use simple sugars for immediate energy.
Typically end with -0se.
Examples: glucose, sucrose, fructose, galactose, lactose, etc.
These look like one or two carbon rings.

fructose
sucrose
glucose

6. Carbohydrates
Complex – more than two simple sugars linked together; used for storage.
Animals store simple sugars in long chains called “glycogen” for future use.
Plants store simple sugars in long chains called “starch” for future use and long chains called “cellulose” for structural support.
Examples: glycogen, starch, cellulose
These look like chains of carbon rings.

9. Carbohydrates
When organisms have extra simple sugars and need to store that energy, they put the simple sugars together using dehydration synthesis to make complex carbohydrates.
When organisms need to use their stored energy, hydrolysis breaks the chains back down into simple sugars.

10. Friday Quiz Announcement
We will be starting in class Go Formative quizzes every Friday
Why?
This will help in studying our notes in small chunks at a time instead of many all at once for a test
You will also get to see how you’re doing from that week’s notes
