Macros, Enzymes, and Metabolic Disorders

Which protein helps speed up chemical reactions?

• Enzymes

• Transport Protein

• Antibodies

• Collagen

What is created or produced in a chemical reaction is known as...

• Substrate

• Enzyme-Substrate Complex

• Enzyme

• Product

If you change the shape of an enzyme, will it work the same/properly?

• Yes

• No

Which of the following conclusions can be drawn from this graph?

• The optimum pH of the enzyme is 6.6.
  
• The optimum pH of the enzyme is 5.8
  
• The enzyme’s activity increases as pH increases 5.0 to 9.0
  
• The enzyme’s activity is greater around pH of 8.0 .
  

What happens when enzymes are heated to a high temperature?

• The enzymes die.
• The shapes of the enzyme are altered or denatured
• The enzymes' amino acid sequence changes.
• The enzymes remain the same

This is one job proteins do NOT have in the body

• storing genetic information
• structure
• speed up chemical reactions
• transport things through cell membrane

Which macromolecule is used as our main source of energy?

• Lipids/Fats

• Nucleic Acids

• Proteins

• Carbohydrates

Lipids provide

• quick energy and insulation

• stored energy and the bulk of the cell membrane

• acceleration for reactions and structure

• a crucial part of the immune and digestive systems

Hydrogen bonds allow for portions of a polypeptide to form alpha helices and beta pleated sheets. This constitutes a protein's _____________ structure.

• secondary

• primary

• tertiary

• quaternary

Due to attractions and repulsions between hydrophilic and hydrophobic R-groups, the polypeptide will fold into a 3D structure. These and other interactions contribute to the polymer's __________________ structure.

• quaternary

• primary

• secondary

• tertiary
