Why Cells that carry on digestion within the cell do not partly digest themselves because they secrete their digestive enzymes into membrane-enclosed?
Cells that carry out digestion internally, such as lysosomes, contain digestive enzymes that are enclosed within membrane-bound compartments. This membrane prevents the enzymes from coming into contact with the cell's own structures, thereby protecting the cell from self-digestion. Additionally, the acidic environment inside lysosomes is optimized for enzyme activity, ensuring that they effectively break down substrates without harming the cell itself. This compartmentalization is crucial for maintaining cellular integrity and function.

How is the increased complexity of the earthworm's digestive system related to segmentation?
The earthworms digestive system is increased in complexity because of the earthworm's segmentation. On each stop or segmentation there is a sphincter and its own digestion going on.
Why does digestion takes place in the stomach mostly?
Digestion primarily takes place in the stomach due to its acidic environment and the presence of enzymes like pepsin, which help break down proteins. The stomach also churns and mixes food with digestive juices to facilitate the breakdown process. Once partially digested, food moves to the small intestine for further digestion and absorption of nutrients.
Explain why chemical digestion does not begin in the mouth for all foods?
Chemical digestion in the mouth primarily involves the breakdown of carbohydrates by the enzyme amylase in saliva. Not all foods require significant carbohydrate digestion, such as proteins and fats. Therefore, chemical digestion for these macronutrients begins further down the digestive tract, where specific enzymes like pepsin and lipase are present.
Why are the salivary glandspancreasliver and gall bladder considered accessory glands of the digestive system?
The salivary glands, pancreas, liver, and gallbladder are considered accessory glands of the digestive system because they produce and secrete substances that aid in digestion but are not part of the main digestive tract. Salivary glands produce saliva that contains enzymes to begin the breakdown of food, while the pancreas secretes digestive enzymes and bicarbonate into the small intestine. The liver produces bile, which helps emulsify fats, and the gallbladder stores and concentrates bile for release during digestion. Together, these glands support the digestive process by enhancing the breakdown and absorption of nutrients.
Explain why a person without a gallbladder is unable to digest fats as efficiently as someone who has a gallbladder?
The gallbladder stores and releases bile, which helps in the digestion and absorption of fats. Without a gallbladder, there is no storage site for bile, leading to a continuous but lower flow of bile into the digestive system. This can result in insufficient bile to properly emulsify fats and impair their digestion and absorption, leading to digestive issues like diarrhea and fatty stools.
Is limoncello considered a digestive?
Yes, limoncello is considered a digestive because it is often consumed after a meal to aid in digestion.
Digestive juices in the digestive tract include?
Mechanical digestion is the same thing as chewing, or mastication. It does not need any digestive juices, because that is considered chemical digestion. Chemical digestion in the mouth during chewing is mainly by the aid of saliva which has, among other enzymes, salivary amylase which initiates carbohydrate digestion.
How is digestion related to psychological stress?
The symptons of psychological stress is related to digestive because its one f many causes of gastrointestinal disorders (digestive system). .
Is the esophagus chemical digestion or mechanical digestion?
No chemical or mechanical digestion occurs in the esophagus, only propulsion, which is one of the six digestive processes.
Does having more stomachs make an animal's digestion more efficient?
Yes. They do Because animals digestive system is slower than humans. Yes. They do Because animals digestive system is slower than humans.
Why is mechanical digestion important for proper chemical digestion?
Mechanical digestion chops the food in to smaller pieces, thus exposing more of it to the enzymes of the chemical digestion.Mechanical digestion begins in the mouth by the teeth, tongue and saliva. Mechanical digestion is important for chemical digestion because when food is broken down into smaller particles by mechanical means, chemical digestion will be more efficient.
Why is it important to chew your food thoroughly before you swallow?
It is important because that is where the digestion begins. If you do not do it properly then it will be harder for your for to digest it. It will also take longer.
Where does the chemical digestion of lipids begin?
In the mouth Precisely in the salivary glands because there are enzymes that are being produced
Explain the process of digestion if a student puts a plain cracker in their mouth, chews it, and holds the mush in their mouth.?
because of the digestive system
How are the digestive and respiratory systems interdependent?
RESPIRATORY SYSTEM is the process of respiration. The lungs is the main organ of the respiratory system because it receives oxygen and take out the carbon dioxide. DIGESTIVE SYSTEM is the process of digestion. The main organ is the stomach because this is where the digestion occurs.
Why are the stomach and mouth near to the start of the digestive system?
This is because the mouth mechanically chew up your food for it to be safely swallowed and go through the stomach for it to digest. After it have been digested the digestive system will absorb the nutrients an acids for our body to function. Then the food has to come out and the digestion has been done.
Does moss have a digestion system?
Sort of. The "digestive system" of a plant is photosynthesis, because that's how they capture nutrients and produce/break down food.
