What are the subunits that polymerize to form starches?
The subunits that polymerize to form starches are glucose molecules. Glucose molecules link together through glycosidic bonds to form starch polymers. Starch is composed of two types of polymers: amylose, which is a linear chain of glucose molecules, and amylopectin, which is a branched chain of glucose molecules.
What does a monomer need in its structure to undergo addition polymerisation?
The monomer must be able to form stable covalent chemical bonds between units in order to polymerize.
What cell part allows only certain substances to difuse into and out of the cell?
The cell's membrane allows only certain substances to diffuse in and out of the cell.
What does Selective permeability do?
It allows the passage for certain substances.
Exposing certain substances to radiation is known as?
irradiation
How many molecules are in certain substances?
it depends on the substance
Why is it important for digestive system functions that mucous membranes can secrete and absorb substances?
The moucous membranes in your body protect certain organs, like the inside of your stomach, from various things. By being able to secrete and absorb substances, the organs these membranes are around are protected.
How do you make change glucose into starch?
Enzymes polymerize glucose into starches.
What are non commutative substances in chemistry?
Non-commutative substances in chemistry are elements or compounds that do not follow the commutative property. This means that the order in which they interact or combine can affect the outcome of a reaction. An example of a non-commutative substance is hydrogen peroxide (H2O2), which can react differently depending on the order of reagents added.
Why is a cell membrane called semi-permeable or selectively permeable?
As the cell membrane only allows certain substances to enter or leave the cell, meaning that while it IS permeable (as some substances can cross it), it is only selectively as not all substances are able to cross it, only some.
What part allows only certain subsTances to diffuse into and out of the cell?
The cell part that allows only certain substances to diffuse into and out of the cell is called the semi permeable membrane. This allows good substances to enter the cell.
What allows only certain substances into the cell?
The cell membrane.
