What is the difference between oxidative and hydrolytic enzymes?
Hydrolytic rancidity involves reacting with water to break ester bonds. A fatty acid and glycerol is formed in this process.On the other hand, oxidative rancidity involves oxygen reacting with the C=C double bond of the lipid.
What produces enzymes that destroy free radicals?
Antioxidant enzymes like superoxide dismutase, catalase, and glutathione peroxidase are produced by the body to neutralize and destroy free radicals. These enzymes help prevent cellular damage and oxidative stress caused by free radicals.
How are proteins destroyed and what factors contribute to their degradation?
Proteins are destroyed through a process called proteolysis, where enzymes break down the protein molecules into smaller fragments. Factors that contribute to protein degradation include pH levels, temperature, presence of enzymes, and oxidative stress.
What is present within the mitochondria that allows the reaction to occur?
The mitochondria contains enzymes and proteins that facilitate the reactions involved in cellular respiration, which produces ATP (adenosine triphosphate) for energy. Important components like the electron transport chain and ATP synthase are embedded in the mitochondria's inner membrane, allowing for the process of oxidative phosphorylation to take place efficiently.
Which color fibers are slow oxidative fibers?
Slow oxidative fibers are typically red in color due to their high myoglobin content, which gives them their oxidative capacity for sustained contractions over long periods of time.
Description of oxidative enzymes?
Oxidative enzyme is an enzyme that catalyzes the reaction of oxides. There are two types of oxidative enzymes, which are the peroxidases and oxidases.
What organelles are small vacuoles containing oxidative enzymes?
Peroxisomes are small organelles containing oxidative enzymes that break down fatty acids and neutralize toxins in the cell. They also play a role in the synthesis of phospholipids and cholesterol.
Why bacteria cell membrane acts as a respiratory structure?
because it contains oxidative enzymes
What contains oxidative enzymes?
Oxidative enzymes are primarily found in organelles called peroxisomes and mitochondria within cells. These enzymes, such as catalase and oxidases, play crucial roles in various metabolic processes, including the breakdown of fatty acids and the detoxification of harmful substances. They facilitate oxidation-reduction reactions, often involving the transfer of electrons and the production of reactive oxygen species. Additionally, oxidative enzymes are present in certain microorganisms and plants, where they contribute to processes like respiration and photosynthesis.

What organelle processes oxidase enzymes?
They are in peroxisomes.They engage in detoxifying.
Which organelles are responsible for the release of destructive enzymes in alzheimers?
Most likely the mitochondria (with respect to oxidative stress and apoptosis) and the endoplasmic reticulum.
What produces enzymes that destroy free radicals?
Antioxidant enzymes like superoxide dismutase, catalase, and glutathione peroxidase are produced by the body to neutralize and destroy free radicals. These enzymes help prevent cellular damage and oxidative stress caused by free radicals.
Where was the term luciferase derived from?
Luciferase is a term for the class of oxidative enzymes used in bioluminescence. The term is derived from the world "Lucifer", which means light bearer.
When might use slow-oxidative fiber and when do you use fast-glycolytic fibers?
Slow Oxidative: These muscle fibers twitch at a very slow rate and are very resistant to fatigue. The peak force exerted by these muscles is also very low. Slow muscle fibers have a lot of oxidative enzymes but they are low in ATP activity. Slow oxidative fibers are used for aerobic activities Fast-glycolytic fibers: Some muscle fibers can contract at a fast rate and produce a large peak force while being resistant to tiring even after many cycles. These fibers are have a large ATP activity and are high in oxidative and glycolytic enzymes. These fibers are used for anaerobic activities that need to be sustained over prolonged intervals of time.

Which organelle produces peroxisomes?
Peroxisomes are organelles present in all eukaryotes. They are present everywhere in an eukaryotic cell taking part in the secretory pathways and there by getting rid of the toxic wastes from the cell. They contain oxidative enzymes that aid in oxidative reactions like the beta -oxidation of fatty acids.
