Macromolecules Rengagement & Eco Levels of organization

What is the primary function of carbohydrates in living organisms?

• Source of energy

• Regulating body temperature

• Storing genetic information

• Building cell walls

Name the three main types of carbohydrates and provide an example of each.

• Proteins, Lipids, Nucleic Acids

• Starch, Cellulose, Chitin

• Glucose, Fructose, Sucrose

• Monosaccharides, Disaccharides, Polysaccharides

What are the two main categories of lipids? Provide an example of each.

• Fats and phospholipids

• Minerals and water

• Nucleic acids and vitamins

• Proteins and carbohydrates

What are the building blocks of proteins?

• Amino acids

• Nucleic acids

• Carbohydrates

• Lipids

What is the function of proteins in living organisms?

• Proteins provide energy through photosynthesis

• Proteins are responsible for storing genetic information

• Proteins provide structural support, enzymatic activity, and transportation of molecules.

• Proteins help in maintaining the water balance in the body

What are nucleic acids and what is their role in cells?

• Nucleic acids are responsible for cell structure and support, similar to proteins.

• Nucleic acids are small molecules that provide energy to cells.

• Nucleic acids are only found in plant cells and have no role in animal cells.

• Nucleic acids are macromolecules that store and transmit genetic information. Their role in cells is to carry the genetic instructions for the development, functioning, growth, and reproduction of all known organisms.

Which of the following describes #2?

• An ecosystem is the interaction between biotic and biotic factors.

• A community is a group of different populations in the same area.

• An organism is one living thing.

• A population is a group of the same organisms.

What level of ecological organization do the organisms represent?

• Species

• Population

• Community
