Which type of molecule includes a long chain carbon backbone

Biology
1 answer:
tester [92]4 years ago
5 0

Answer:

Although lipids have a "backbone," they are not true biological polymers as their backbone is a three carbon molecule, glycerol, with longer substituent "side chains." For this reason, only proteins, carbohydrates, and nucleic acids should be considered as biological macromolecules with polymeric backbones.

d1i1m1o1n [39]

Answer:

1. releases bile to break down fat

pancreas

2. helps break down protein

liver

3. remove carbon dioxide from the body

lungs

4. breaks down starch into sugar

saliva

5. absorbs nutrients into the blood

small intestine

6. absorbs extra water from undigested food

large intestine

Explanation:

The main functions of saliva is digestive function: moisturizes and softens the morsel; the saliva contains the enzyme ptialin that breaks some starches down into maltose and dextrin.

The large intestine is the largest internal organ; its role is the absorption of food, nutrients and water.

Hepatic Cells - Hepatocytes have many metabolic functions that enable them to have a rich blood supply.All hepatocytes participate in metabolism. processing of proteins, fats, carbohydrates, bile color - bilirubin, bile acids, vitamins, minerals and some hormones. Food proteins broken down to their constituents - amino acids, are used by the liver as a building material for the synthesis of its own proteins and plasma proteins, which have different vital functions in the body.

In the small intestine, digested food is converted to liquid and goes to blood.

Pancreas secretes the enzymes amylase and lipase (which are mainly used to dissolve fats) and participates in the chemical breakdown of food to absorb molecules into the blood.

Give an example of a stimulus, and explain how your nervous system and muscular system work together to respond to it.
zhuklara [117]
One example of stimulus is reacting to a hot pan. If you touch it, you immediately pull your fingers back. This is your nervous system sending alerts through your body, and to your muscular system. Your muscular system allows you to bend your arm, and move your fingers away from the hot pan. 
:) Hope this helps!

What is the main advantage of the c4 and cam photosynthesis strategies?
klio [65]
The main advantage of C4 and CAM plants are that they have specially adapted metabolic pathway in order to limit exposure of Rubisco enzyme to oxygen (oxygen can inhibit Rubisco and reduce photosynthesis that way). Photorespiration is a process when Rubisco reacts with oxygen rather than with carbon dioxide. C4 plants and CAM plants tend to minimize photorespiration. C4 plants separate steps of CO2 fixation and Calvin cycle in two different cell types. CAM plants separate these steps in time, between night and day.
