Enzymes are proteins that have a three-dimensional shape that is specific to a particular substrate. Environmental conditions can change the shape of the protein.
What is the most likely result if the shape of the enzyme changes?

The enzyme will be able to bind to more diverse substrates than before.

The substrate will change its shape to match the enzyme.

The enzyme will no longer be able to catalyze the reaction with the substrate.

The products made from the enzyme and the substrate will be changed.

ENZYME RUBRIC LINK
Penicillin is an antibiotic (medicine) that a doctor may prescribe you if you are feeling sick. Penicillin works by inhibiting (stopping) the enzyme transpeptidase from properly forming the cell walls of bacteria cells.
A diagram representing the process of penicillin (enzyme inhibitor) acting on transpeptidase (enzyme) is shown below.
Will the enzyme be able to catalyze the reaction with the substrate properly? Explain why or why not.
Look at the diagram carefully. Then enter your answer and explanation in the box provided.

People who have Alzheimer's disease experience an increasing loss of brain function and cognition over time. Alzheimer's is characterized by a building of abnormal protein fragments that damage brain cells. Recently scientists have discovered an enzyme, BACE2, that decreases these abnormal protein fragments in the brain of a person with Alzheimer's diseases.
Which statement explains how BACE2 most likely works?

BACE2 breaks down into smaller pieces that react with the abnormal protein fragments, forming more complex molecules.

BACE2 is a reactant that combines with the abnormal protein fragments.

BACE2 speeds up the reaction that breaks down the abnormal protein fragments.

BACE2 molecules link several abnormal protein fragments together, forming a complete protein.

Short Answer: Enzymes -
Raw shrimp and fish can contain bacteria, including disease-causing bacteria. These bacteria, like all living organisms, contain proteins. Remember proteins are vital to the health and functioning of the organism.
Choose ONE of the following prompts to respond to:
Describe what occurs in disease-causing bacteria when shrimp and fish are cooked (on the grill, in the oven, on the stove, etc.) - Identify temp change / denatured
Ceviche is a dish where raw shrimp and fish are soaked in lemon or lime juice, which has a very low pH, for many hours. Explain why it is safe to eat ceviche. - pH changed / enzyme denatured (bacteria dies)
*Make sure your answers describe the reaction between the oven, enzymes, and proteins at play when food is cooked in the oven versus when it is made using the ceviche method.
