As a cell increases in size the a. metabolic rate increases. b. surface area to volume ratio increases. c. volume increases and the surface area increases. d. surface area increases and the volume d?
As a cell increases in size the volume increases much faster than the surface area. The possible answer is C.
If the volume of a cell increases its surface area will?
it increases
Could chemical digestion take place if mechanical digestion did not occur?
Mechanical digestion, i.e. your body breaking up the food into smaller pieces, is largely meant to speed chemical digestion up. We know that the rate at which the chemical reaction takes place is dependent on four things: the physical state of the reactants involved in the reaction, the temperature at which the reaction takes place, the concentration of the reactants, and the presence of a catalyst. Each influences the rate of reaction in different ways. Mechanical digestion breaks the food into smaller pieces, i.e. changes the physical state. With the larger pieces broken into smaller ones, more surface area is exposed. With greater surface area exposure, chemical digestion can take place much more rapidly. However, if for some reason you could get just huge chunks of food down your throat without chewing it, your stomach still churns (mechanical digestion) and the contractions in your intestines also help to break up food. So technically yes, chemical digestion would take place, but at a much slower and inefficient manner.
Is as cell surface area increases cell volume increases faster true?
Yes
What then is the main purpose of mechanical digestion?
to break down the food that we eat, allowing the body and use the useful parts of the body to help us get our food out of our system after we eat it. it makes it small and takes the nutrients out to store
Which process increases the surface area of foods prior to chemical digestion?
chewing
What is the effect of an emulsifier on the digestion of liquids?
During emulsification process the surface area of fat increases million times. This allows to have contact of fat and fat spitting enzyme very well. Thus it helps in digestion of the fat.
Why is it helpful to have rocks broken into smaller and smaller pieces?
It is helpful because it increases surface area available for the chemical weathering process.
How thousands of folds and sub-folds in the small intestine help in digestion?
It increases the surface area available for absorption of digestion nutrients.
The rate of chemical weathering increases with this?
surface area
Difference between physical digestion and chemical digestion?
Physical (also called mechanical) digestion is when you use your teeth to mash up food. You are physically breaking the food into smaller pieces. However, chemical digestion would be what your saliva or stomach acids are doing. They are breaking down the food and transferring different parts of it (such as lipids etc.) to the different parts of your body that need it.
What is the mechanical digestion that prepares the food for the digestion?
Digestion can be mechanical or chemical. Mechanical digestion is the process of physically (i.e. not involving biochemical enzyme) breaking food down into smaller pieces, creating a greater surface area for chemical digestion to take place. Examples of mechanical digestion include the churning motion of your stomach and obviously, the chewing process of your mouth. Chemical digestion, on the other hand, requires the presences of enzymes to trigger chemical reaction and break the food particles down to simpler substances. Examples include the salivary amylase breaking down sugar, stomach acid and gastric enzymes breaking down proteins, and the lipase breaking down lipids in the small intestine.
How are physical changes used in the digestive process?
There are a few physical changes that take place during digestion. Chewing food to reduce the size of the pieces and also gives the enzymes and other things more space to act on. Another is churning which is found in the stomach. Here the food is moved around somewhat like what happens in a mixing bowl. And the last is peristalsis which is a physical movement seen in the tract from the esophagus to the anus.
How does microvilli help in the digestion of food?
The provide the small intestine with a large surface area, and provides the capillaries close to the surface.
How do you alter the reaction rate of a chemical change?
Heat - increases it Increased stirring - increases it larger surface area - increases it catalyst - usually increases it and the reverse of the above slows the reaction down
Are teeth chemical or mechanical digestion?
Salivary Glands performs Chemical Digestion
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.
