What substance most easily travel across a cell membrane?
Substances that pass most readily into a cell are ions. They are transferred through ion channels that are made specifically for this purpose.
Which substances readily diffuse through the membrane?
Small and non-polar molecules can readily pass through the cell membrane. They follow the concentration gradient, moving from the higher concentration area to the region of lower concentration.
Do larger molecules diffuse more readily than smaller molecules?
No, smaller molecules generally diffuse more readily than larger molecules because they can move through pores and gaps in substances more easily due to their smaller size. This is why smaller molecules like oxygen and carbon dioxide can diffuse through cell membranes more quickly than larger molecules like proteins.
Which substance could pass through the cell membrane readily?
Small molecules, such as water, oxygen, and carbon dioxide.
Glucose molecules do not have to be digested starch molecules do explain the difference?
Glucose molecules are simple sugars (monosaccharides) that can be directly absorbed into the bloodstream without any further breakdown. In contrast, starch is a complex carbohydrate made up of many glucose units linked together, which must be digested by enzymes into individual glucose molecules before they can be utilized by the body. This digestion process involves breaking the glycosidic bonds between glucose units, making starch a more complex source of energy compared to readily available glucose.
2 substances that don't pass out of blood?
Red blood cells and large proteins are two substances that typically do not readily pass out of the blood vessels into surrounding tissues.
Each sucrose molecule is hydrolyzed in the small intestine to form one molecule of what?
The sucrose molecules are broken down in the molecules of glucose which is the simplest form od the saccharides. The sucrose in the body is not readily metabolized but it has to be broken down into simpler form of molecules. The glucose is easily metabolized int he body.
Why is glycogen soluble?
Glycogen is soluble because it is composed of many glucose molecules linked together in a branched structure. These glucose molecules are hydrophilic, meaning they are attracted to water and can readily dissolve in it. This solubility allows glycogen to be stored in cells and readily broken down to release glucose when needed for energy.
Which substance dissolves most readily in gasoline?
Nonpolar substances such as oils, grease, and tar dissolve most readily in gasoline due to their similar nonpolar nature. Gasoline is a nonpolar solvent, meaning it tends to dissolve other nonpolar substances more readily than polar ones.
The potential energy of organic molecules is most readily available to cells in the form of?
The potential energy of organic molecules is most readily available to cells in the form of adenosine triphosphate (ATP). ATP is the primary energy currency of cells and is generated through the breakdown of organic molecules such as glucose during cellular respiration. Cells can quickly access the energy stored in ATP to power various biological processes.
What is the different between animal and plant starch?
Animals do not store glucose in starch molecules, but rather in glycogen molecules. Starch molecules have infrequent branching of glucose chains and as such are not readily broken down into glucose monomers by the enzymes that catalyze the reaction. Glycogen molecules follow the same basic structure as starch molecules, but instead have more branching and consequently are broken down easier. This allows for quicker "burst" energy and is better suited to animals' mobility.
What food molecules is easily absorbed?
Vitamin C molecules, water molecules and glucose molecules are very easily absorbed because they don't have as many particles as starch molecules, protein molecules and fat molecules.
