Glucokinase is the enzyme responsible for phosphorylation of glucose in the first step of glycolysis. The glucokinase complex is modified by two different molecules: citrate and ATP. Citrate and ATP are both products of the sequence of reactions in aerobic respiration and are consequently products of glycolysis. As these two molecules' concentrations in the cell build up, they bind to the allosteric site of glucokinase and shut it down.

How do the saprophytes feed on the rotten materials?
Saprophytes, or saprophytic organisms, feed on rotten materials by breaking down dead organic matter through a process called decomposition. They secrete enzymes that digest complex organic substances into simpler compounds, which they then absorb. This process not only allows saprophytes to obtain nutrients but also recycles essential elements back into the ecosystem, supporting new plant growth. Examples of saprophytes include fungi and certain bacteria.
How does amoeba feed?
Amoebas feed by engulfing food particles through a process called phagocytosis. They extend their pseudopods around the food particle, forming a food vacuole that contains the particle. Digestive enzymes are then secreted into the food vacuole to break down the food for absorption.
What feeds by the secretion of extracellular enzymes on food?
Fungi and some bacteria feed by secreting extracellular enzymes onto their food source, breaking down complex molecules into simpler forms that can be absorbed for nutrition. This process is known as external digestion and allows these organisms to access nutrients from a wide range of organic materials.
What is vesicles parasites?
Vesicles are small sacs or blisters that parasites can form to help them move, feed, or reproduce. They can contain various materials such as digestive enzymes or waste products, and play a role in the parasite's lifecycle and interactions with its host.
Does the endocrine system often run on negative feed back?
Endocrine system usually uses the negative feed back mechanism. So suppose when thyroid stimulating hormone is released, then thyroid hormones are released. They reduce the secretion of thyroid stimulating hormone. This is how the secretions of the hormones is regulated. In positive feed back mechanism, the level of both the hormones will raise and will create lot of problems.
How is the cell cycle monitored?
It is regulated by various enzymes and negative feed-back mechanisms.
Do enzymes slow down reactions in your body?
No, they speed them up by lowering the activation energy of reactions. The body has other ways to slow reactions. Concentration of enzymes, inhibition of enzymes, sometimes by negative feed back mechanisms.
In the stomach feed is broken down by what?
Enzymes.
How is oxytocin an example of a hormone that is under positive regulaton?
Yes it is an example. There a positive feed back mechanism take place
What are the enzymes in poultry feed?
Enzymes in poultry feed are natural proteins added to feed to help birds digest food better. They break large nutrients into smaller parts, so chickens can absorb more nutrition. This helps improve growth, health, and overall performance. Using the right enzymes in poultry feed also helps reduce feed waste. Main enzymes in poultry feed Phytase Breaks down phytate and releases phosphorus. This supports strong bones and reduces mineral loss in waste. Protease Helps break protein into amino acids. It improves muscle growth and better protein use. Amylase Breaks starch into simple sugars. This gives birds more energy for daily activity and growth. Lipase Helps digest fats into fatty acids. It improves energy use and supports weight gain. Xylanase & Beta-glucanase Break down fiber (NSP) in grains like wheat. They improve digestion and reduce sticky droppings. Cellulase & Mannanase Help break tough plant fibers. This increases nutrient availability from feed ingredients. Why enzymes in poultry feed are important Improve digestion and nutrient absorption Increase feed efficiency and bird growth Reduce feed cost by better nutrient use Improve gut health and litter quality Help use cheaper raw materials effectively Reduce environmental waste from farms Useful tip Choose enzymes based on your feed ingredients. For example, use fiber-digesting enzymes if your feed contains more wheat, maize bran, or rice bran. Conclusion Enzymes in poultry feed play a very important role in modern poultry farming. They help birds get more nutrition from the same feed, which saves cost and improves performance. Better digestion also means healthier birds and less waste. By using the right mix of enzymes in poultry feed, farmers can improve growth rate, feed conversion ratio (FCR), and overall farm profit.

Are the feed additives potassium chloride e508 stpp e451 modified starch e1442 and edta e385 regulated in the eu?
No, potassium chloride, E508 stpp, e451 modified starch, E1442 and Edta e385 are not closely regulated in the EU. These things can all be legally added to feed for animals and food for humans.
What is the concept of homeostasis.?
there are many homeostatic systems which are maintained by feed back loops. a good example is red blood cell production (erythropoesis)
