Biological Molecules Quiz

You are a scientist studying different food items. How would you determine if a food item is a carbohydrate?

• Look for a carbon ring structure in its molecular composition

• Check if the elements are in a 1:2:1 ratio

• Check if the elements are in a ratio greater than 1:2:1

• It has a carbon chain structure

Answer explanation

as you can see this is a carbon ring, one of the factors in defining whether a carbohydrate is actually a carbohydrate.

In a biology lab, a scientist is studying a macro-molecule lipid. Which monomer would he likely be focusing on?

• phosphate

• DNA/RNA

• fatty acid

• amino acid

A chef is preparing a dish that requires a macro-molecule protein. Which ingredient should he use as the monomer?

• insulin

• amino acid

• polymerase

• peptide bond

A scientist is studying the structure of a macro-molecule carbohydrate in her lab. She needs to identify the monomer that matches with this macro-molecule. What could it be?

• fibers

• starches

• nucleic acid

• monosaccharide

which macro-molecule matches these examples:

nucleotide:

sugar, phosphate, nitrogenous base.

(a)  

are looking at two different types of cells under a microscope - one is a prokaryotic cell and the other is a eukaryotic cell. What would be the main difference you would notice?

• Prokaryotic cells are larger than eukaryotic cells
• Prokaryotic cells have a nucleus, while eukaryotic cells do not
• Prokaryotic cells contain mitochondria, while eukaryotic cells do not
• Prokaryotic cells do not have a nucleus, while eukaryotic cells do

eu l true

karyon l nucleus or kernel

use the table to find the definition of a eukaryote

• with nucleus but not nucleolus

• nucleus is true to the cell

• true that is was before the cell

• without nuclei

what organelles do both eukaryotes and prokaryotes share?

• mitochondria, cell wall, and ribosomes.

• ribosomes, cell wall, and cytoplasm.

• endoplasmic reticulum, golgi, and cytoplasm.

• golgi, mitochondria, and cell wall.

What are the three components that make up the cell theory?

• Nucleus, Mitochondria, Ribosomes
• Prokaryotic, Eukaryotic, Multicellular
• All living things are made up of cells, Cells are the basic units of structure and function in living things, New cells are produced from existing cells
• DNA, RNA, Proteins
