What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
What food molecules is easily absorbed?
Simple sugars such as glucose and fructose are easily absorbed by the body because they can be broken down quickly and readily enter the bloodstream. Amino acids found in proteins are also easily absorbed, as they are the building blocks of protein and readily utilized by the body for various functions. Medium-chain triglycerides are another example, as they are a type of fat that can be easily broken down and absorbed by the digestive system.
Describe the conditions needed for molecules to enter a cell passively?
Molecules can enter a cell passively through processes like simple diffusion or facilitated diffusion. For this to occur, the molecule must be small, nonpolar, and/or able to pass through ion channels or carrier proteins. Additionally, there must be a concentration gradient across the cell membrane to drive the movement of molecules into the cell.
What are molecules that are joined in an ordered structure?
When molecules are linked in organized positions has solid results. When heat is absorbed by a solid the molecules vibrate faster and faster.
What is the process called by which food is broken down and nutrition is extracted?
The process is called metabolism.Digestion is the mechanical and chemical breaking down of food into smaller components that can be absorbed into a blood stream,
