Question 1A) All biomolecules have the following traits except (1 point) nitrogen elements. covalent bonds. a carbon backbone. hydrogen elements.

Question

Question 2 A) What enzyme breaks down starch in your saliva? (1 point) lipase trypsin pepsin amylase

Question 3 A) Which soil-based compounds do plants use to create amino acids from glucose? (1 point) carbon fluoride hydrogen nitrogen

Question 4 A) What are the building blocks of proteins? (1 point) sugars amino acids fatty acids starch

Question 5 A) How are carbohydrates related to the structure of cells? (1 point) Cellulose makes up the cell wall in plants, helping the cell have a rigid outer layer. Chitin is embedded in cell walls to help move molecules into and out of the cell. Monosaccharides make up fifty percent of the cell membrane, helping the cell maintain its shape. Glucose makes up the exoskeleton of insects, protecting them from the environment.

Answer 1

Here are the answers to your questions:

Question 1A) All biomolecules have the following traits except:

• Nitrogen elements. (Not all biomolecules containing carbon, hydrogen, and covalent bonds contain nitrogen; for example, carbohydrates do not necessarily contain nitrogen.)

Question 2 A) What enzyme breaks down starch in your saliva?

• Amylase.

Question 3 A) Which soil-based compounds do plants use to create amino acids from glucose?

• Nitrogen. (Plants require nitrogen to synthesize amino acids from glucose.)

Question 4 A) What are the building blocks of proteins?

• Amino acids.

Question 5 A) How are carbohydrates related to the structure of cells?

• Cellulose makes up the cell wall in plants, helping the cell have a rigid outer layer. (This is a correct statement about the role of carbohydrates in cell structure.)
