Lab #9 Enzyme Function

What is the primary role of enzymes inside of living cells? 

• organizing the translation of proteins
• allowing cells to be motile
• absorbing ultraviolet rays
• speeding up chemical reactions 

Based on their role in the cell, enzymes can also be classified as –

• inhibitors
• catalysts
•  hormones
• vitamins

Enzymes are a form of which biomolecule? 

• carbohydrates
• proteins
• nucleic acids
• lipids

Enzymes are composed of which of the following monomers? 

• amino acids
• acyl groups
• nucleotides
• monosaccharides

The role of enzymes in the cell is best summarized by which of the following statements?  

• They control the reaction rate of processes within the cell. 
• Enzymes carry the blueprints for the entire cell. 
• They send signals through the bodies of multicellular organisms. 
• Enzymes protect the skin from harmful radiation.

Where do substrates bind on an enzyme?

• voltage-gated channels
• surface receptor
• calcium channels
• active site

What is structure A?

• Substrate
• Active site
• Enzyme
• Products

What is structure D?

• Substrate
• Active site
• Enzyme
• Products

What is structure E, F, G?

• Substrate
• Active site
• Enzyme
• Products

What is a Substrate?

• it speeds up enzyme substrate process
• the reaction of an enzyme
• proteins that act as biological catalyst
• it slows down enzyme substrate process
