AP BIO 1st Semester Final

Front

What is the relationship between dehydration reactions and hydrolysis?

Back

Dehydration reactions assemble polymers, and hydrolysis breaks down polymers.

Front

What is the advantage of compartmentalization in cells?

Back

It prevents reactions from interfering with one another.

Front

Which process is incorrectly matched with its location: Glycolysis, Krebs Cycle, Light reactions, or Calvin Cycle?

Back

Calvin Cycle = inner mitochondrial membrane.

Front

Which organelle is responsible for protein modification and packaging?

Back

Golgi apparatus.

Front

What is a model of active transport?

Back

A membrane protein binds a specific molecule outside of the cell and moves the molecule into the cell where there is already a high concentration of the molecule compared with the outside.

Front

Define dehydration reaction.

Back

A chemical reaction that involves the loss of a water molecule from the reacting molecule, typically used to form polymers.

Front

Define hydrolysis.

Back

A chemical reaction that involves the addition of water to break down polymers into monomers.

Front

What is the function of the Golgi apparatus?

Back

To modify, sort, and package proteins and lipids for secretion or delivery to other organelles.

Front

What is the role of ribosomes in the cell?

Back

Ribosomes are the sites of protein synthesis, translating mRNA into polypeptide chains.

Front

What is the Krebs Cycle?

Back

A series of enzymatic reactions in the mitochondrial matrix that produce energy through the oxidation of acetyl-CoA.
