The goal of digestion is to break down food to the glucose level. Only then will it be absorbed into the cell and be used in respiration.
When a large molecule enters a cell, it is typically transported through the process of endocytosis. This can occur via phagocytosis for solid particles or pinocytosis for liquid particles. The cell membrane surrounds the large molecule forming a vesicle that is then taken into the cell.
facilitated
Transport protiens are open on the outside and the molecule goes in the protien and it flips and then it enters the cell.
Facilitated
That is called endocytosis, specifically phagocytosis when the macro-molecule is a solid particle or pinocytosis when it is a liquid. In this process, the plasma membrane surrounds the molecule to form a vesicle, which then enters the cell.
The cell membrane controls what enters or leaves the cell.
No, pyruvate is a molecule produced from the breakdown of glucose during glycolysis.
When a molecule enters the cell through a protein pump, it is classified as active transport. This process requires energy, typically in the form of ATP, to move molecules against their concentration gradient, from areas of lower concentration to higher concentration. In contrast, passive transport does not require energy and occurs along the concentration gradient.
The virus enters the host cell in the penetration phase.
molecule - cell - organ
Digestion is extracellular (outside the cell) and nutrients are absorbed into the cell.
Large molecules can enter cells through processes like endocytosis, where the cell membrane surrounds the molecule and engulfs it in a vesicle. This allows large molecules to be transported into the cell without crossing the lipid bilayer of the membrane.
