Breaking down of large macromolecules to monomers is known as catabolism. More the substance is broken down, larger its surface area gets. A particle with more surface area can be easily be metabolized by our body. Enzymes can act with full tendency on particles that have larger surface area and then an be easily digested and absorbed by out boy.

How does the surface area of a cube change if the length of each side is doubled?
The surface area is quadrupled.
Does the surface area change in the same proportion?
Yes.
How to show that the rate of change of the volume of a cube with respect to the length of its edges is equal to have the surface area of the cube?
If the length of an edge is x, the volume is x3 To find the rate of change of the volume with respect to x, differentiate: d(x3)/dx = 3x2 The area of one face is x2 There are six faces so the total surface area is 6x2 Therefore the rate of change of volume, 3x2 , is half of 6x2 , the surface area.
How can two cylinders have the same surface area but different volume?
Change in height and circumference
What is the surfqace area of a cylinder?
It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh
How does mechanical digestion change the surface area of food?
uses saliva to break into smaller pices
How does the surface area of a cube change if the length of each side is doubled?
The surface area is quadrupled.
Is it true that the mechanical breakdown of food exposes a larger surface area for chemical digestion?
Yes, it is true. The reaction rate depends also on the surface area of the reactants.
What process increases the surface area of foods prior to chemical digestion?
Mastication, or chewing, is a form of mechanical digestion that increases the surface area of foods prior to chemical digestion.
How does cell's ratio of surface area to volume change as the cell grows larger?
because it has the surface area of volume
How does chemical weathering promote mechanical weathering?
Mechanical weathering breaks down the rock into smaller pieces, exposing more surface area. This allows the acid and chemicals to break down the pieces of rock faster.
What is the main thing that mechanical weathering accomplishes that makes chemical weathering more efficient?
Mechanical weathering increases the surface area that can be attacked by chemical weathering.
Does the surface area change in the same proportion?
Yes.
Do the round shape of blood cells gives them extra surface area?
yes because it is like any other object if you change the shape you change the surface area
Why would sharpening a knife or ax blade improve its mechanical advantage?
more pressure on a smaller surface area.
How does a cell's ratio of surface area to volume change as the cell grows larger?
As the cell grows larger the ratio of surface area to volume increases. Larger cell = more volume for the amount surface area.
Does mechanical breakdown increase speed of chemical breakdown?
Yes, mechanical breakdown increases the surface area available for chemical reactions to occur on and therefore the speed of the chemical processes.
