Name the parts of the digestive system which acts like a speed bump to control the movement of food in our alimentary canal.

can someone please answer this quick i really need this..tysm for ur help

circular folds

Explanation:

The movement of food in the body's alimentary canal (the passage of food from the mouth towards the anus) is aided by "peristalsis."

"Peristalsis" is an involuntary movement of the circular and longitudinal muscles found within the digestive tract. This movement occurs in the esophagus, stomach and small intestine.

Along the jejunal intestinal wall are the "circular folds." These folds are thick and stretches towards the "lumen." They function as speed bump control by slowing down the food passage and increasing the surface area necessary for absorption. After being absorbed, they will then be moved forward toward the large intestine.

So, this explains the answer.

It is a true statement.

ATP synthase is the primary functioning of enzymes. A proton pumping transmembrane is powered by ATP hydrolysis which is very important. For example; ATP produces anaerobic bacteria by fermentation then ATP synthase uses ATP which helps to generate proton motive force which is necessary for flagella motility and ion transport.

ATP synthase is in both ways where bacteria can live from photosynthesis or respiration and also in fermentation. In order to avoid wasting ATP hydrolysis, it is significant to control ATP-driven proton by pumping activity.
