Study Notes

Enzyme Functions

The main purpose of enzymes is to facilitate biochemical reactions in the body.

Lactose Breakdown

Lactase is the enzyme that helps break down lactose found in milk.

Aldehyde Dehydrogenase (ALDH)

Aldehyde dehydrogenase (ALDH) in the body helps convert aldehydes into acids.

Carbohydrate Breakdown

Amylase helps change starches into sugars in the salivary glands and pancreas.

DNA Unwinding

Helicase plays a crucial role in unwinding DNA double helix structures during DNA replication.

Maltose Breakdown

Maltase is the enzyme responsible for breaking down maltose into glucose molecules.

Protein Breakdown

Trypsin enzymes break down proteins into smaller peptides and amino acids in the small intestine.

Neurotransmission

Acetylcholinesterase (AChE) breaks down the neurotransmitter acetylcholine, terminating its signal transmission.

Lactose Breakdown

Lactose is the substrate for lactase, which breaks it down into glucose and galactose.

DNA Replication

Helicase enzymes unwind DNA double helix structures, allowing for DNA replication to occur.

Description

This quiz explores the concept of lock and key interactions, drawing parallels between the process of unlocking a lock with a key and the interaction of enzymes with specific substrates in biological systems. It also includes a mix and match section related to enzymes and the processes they catalyze.
