Enzymes are like complex biological catalysts (matter of fact, that's exactly what they are..). They help your body break down certain proteins, vitamins, and other molecules. People who are lactose intolerant lack an enzyme to process lactose (a complex sugar in most milk). They must either drink lactose-free milk, or take certain supplements that introduce lactose enzymes into the body.

Example of membrane bound enzymes?
Membrane bound enzymes are enzymes in a membrane that are responsible for the maintenance of cellular functions such as ion transport, secretion and uptake of a variety of substances, as well as cell to cell interactions. A membrane-bound organelle is an organelle surrounded by a plasma membrane.
What is the antimicrobial enzyme found in tears?
The antimicrobial enzyme found in tears is called lysozyme. It helps to protect the eyes from bacterial infections by breaking down the cell walls of certain bacteria.
If a cell is exposed to cyanide most of the cyanide will be found within?
If a cell is exposed to cyanide, most of the cyanide will be found within the mitochondria. Cyanide inhibits cytochrome c oxidase, a key enzyme in the electron transport chain located in the inner mitochondrial membrane, disrupting cellular respiration and leading to cell death.
What enzyme converts glucose to ethanol during fermentation?
The enzyme responsible for converting glucose to ethanol during fermentation is alcohol dehydrogenase. This enzyme facilitates the conversion of pyruvate to acetaldehyde and then to ethanol in the absence of oxygen.
Why DAB is used in immunoblotting?
DAB (3,3'-diaminobenzidine) is commonly used in immunoblotting as a substrate for the horseradish peroxidase enzyme. When HRP catalyzes the oxidation of DAB, a brown insoluble precipitate forms at the site where the enzyme is located, allowing visualization of the protein of interest on the membrane.
Where will ATPase be found in the mitochondrion?
ATPase is typically found in the inner mitochondrial membrane. This enzyme is involved in producing ATP by catalyzing the conversion of ADP to ATP during oxidative phosphorylation.
Are respiratory enzyme located in mitocondrial membrane?
Yes
Where ETS enzyme located in the mitochondria?
inner membrane
What are the four types of protein in a cell membrane?
The four main types of proteins found in a cell membrane are integral proteins, peripheral proteins, glycoproteins, and channel proteins. Integral proteins are embedded within the lipid bilayer, while peripheral proteins are attached to the surface of the membrane. Glycoproteins have carbohydrate chains attached to them, and channel proteins help facilitate the movement of specific substances across the membrane.
An enzyme and a membrane receptor molecule are similar?
acts as catalysts
Where are membrane proteins are found?
Surprisingly, membrane proteins are found in or attached to the membrane.
The membrane-bound enzyme system that restores and maintains the resting membrane potential is what pump?
The membrane-bound enzyme system responsible for restoring and maintaining the resting membrane potential is the sodium-potassium pump. It actively transports sodium ions out of the cell and potassium ions into the cell against their concentration gradients to establish the resting membrane potential.
Example of membrane bound enzymes?

Can ATP synthase move about in the cytosol of the mitochondrian?
Definitely not, as ATP synthase is a membrane-bound enzyme. It is integrated into the inner mitochondrial membrane (and the thylakoid membrane in chloroplasts).
The activity of acetylcholine in a synapse is terminated by?
Its degradation by a hydrolytic enzyme on the postsynaptic membrane.
A protein on the cell membrane that recognizes and binds to specific substances is called a?
Enzyme
Why lysosomal enzyme do not digest its own membrane?
Because the organs are layered with mucus.
