Question

carbohydrates

1. what three elements do all carbohydrates contain?
2. why does the name carbohydrate make sense based upon the elements this group of molecule contains?
3. what ending do most sugars possess?
4. what is the relationship (ratio) between o and h in carbohydrates?
5. what is the main function of carbohydrates?
6. fill in the table below regarding polysaccharides.

polysaccharide	found in plants or animals	use/function
glycogen

Explanation:

Step1: Answer question 6

All carbohydrates contain carbon (C), hydrogen (H), and oxygen (O).

Step2: Answer question 7

The name "carbohydrate" makes sense because the ratio of hydrogen to oxygen is often 2:1, similar to water (H₂O), and they contain carbon. So it's like "carbon - water".

Step3: Answer question 8

Most sugars possess the ending "-ose", such as glucose, fructose.

Step4: Answer question 9

In carbohydrates, the ratio of hydrogen to oxygen is 2:1. So the ratio of O to H is 1:2.

Step5: Answer question 10

The main function of carbohydrates is to provide energy for the body.

Step6: Answer question 11 - Cellulose

Cellulose is found in plants. Its function is to provide structural support to plant cell walls.

Step7: Answer question 11 - Glycogen

Glycogen is found in animals. Its function is to store energy in animal cells.

Answer:

1. Carbon (C), Hydrogen (H), Oxygen (O)
2. Because H:O ratio is often 2:1 like in water and they have carbon.
3. -ose
4. 1:2
5. Provide energy for the body
6. Cellulose: Found in Plants, Use/Function - Provide structural support to plant cell walls

Glycogen: Found in Animals, Use/Function - Store energy in animal cells
