Membrane digestion refers to the process by which cells incorporate nutrients from the external environment through the cell membrane. This process involves the uptake, processing, and absorption of nutrients such as amino acids, sugars, and lipids by the cell. Membrane digestion plays a crucial role in nutrient acquisition and energy production for the cell.

How is the plasma membrane related to the lysosome?
The plasma membrane surrounds the cell and regulates the movement of substances in and out of the cell. Lysosomes are membrane-bound organelles that contain digestive enzymes to break down waste materials. Lysosomes fuse with the plasma membrane to release their enzymes outside the cell for extracellular digestion.
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.
Vacuoles and vesicles aid in?
Vacuoles and vesicles aid in storage, transportation, and digestion within cells. Vacuoles are large membrane-bound organelles that store water, nutrients, and waste products. Vesicles are smaller membrane-bound sacs that transport molecules within the cell or to the cell membrane for secretion.
What is the large vesicle that aids in digestion within plant cells?
The large vesicle that aids in digestion within plant cells is called a vacuole. Vacuoles are membrane-bound organelles that store water, nutrients, and waste products, and also play a role in maintaining turgor pressure and supporting the structure of the cell.
What type of type of membrane proteins catalyzes reactions the?
Enzymatic membrane proteins, known as integral membrane enzymes, catalyze chemical reactions at the membrane's surface or within its lipid bilayer. These proteins facilitate various biochemical processes, such as digestion and signal transduction, by lowering the activation energy of reactions. They often function as receptors or transporters as well, playing critical roles in cellular communication and metabolism.
Membrane-bound sacs in which digestion occurs are called?
it is called a vacuole
A sac bounded by a single membrane?
A sac bounded by a single membrane is called a lysosome. This organelle is present only in animal cells and contributes in intracellular digestion.
What 3 parts of a cell takes care of ingestion digestion and excretion?
cell membrane, cytoplasm and vacuoles
Will the dissolved oxygen in the water be absorbed during digestion?
Dissolved Oxygen can diffused through the membrane in digestion system by concentration gradient however the amount absorbed should be minimal or negligible.
What involved in the digestion of food within the cell?
Lysosomes are the digestive center within a cell.
How is the plasma membrane related to the lysosome?
The plasma membrane surrounds the cell and regulates the movement of substances in and out of the cell. Lysosomes are membrane-bound organelles that contain digestive enzymes to break down waste materials. Lysosomes fuse with the plasma membrane to release their enzymes outside the cell for extracellular digestion.

What glandular secretion contains some DNA RNA and membrane components such as phospholipids?
Saliva contains some DNA, RNA, and membrane components, such as phospholipids. These components can help protect the oral cavity, aid in digestion, and maintain oral health.
What does the vacuole of a cell do?
A vacuole is a membrane bound sac that plays roles in intracellular digestion and release of cellular waste products.
