Why rate of anaerobic respiration is faster in starch than in glucose?

Infact it should. It is a common misconception that because Glucose is a monosaccharide that it should provide a higher rate of respiration as it does not need to be broken down, unlike sucrose. However, the method the glucose enters the yeast enters the cell is by facillitated diffusion and this requires carrier proteins. When glucose is being absorbed, there will be a point where the rate reaches it's maximum, i.e. all the carrier proteins are being used. When sucrose is the substrate, it is split into glucose and fructose. When all the carrier proteins are used transporting glucose, different proteins are used for fructose (due to the tertiary structure of the protein) so the composite monosaccharides of sucrose can enter the yeast at a higher rate. Hence the rate is faster.

Do enzymes change starch into glucose?
Yes they do. Enzymes change starch into glucose for cellular respiration.
Is starch used in cellular respiration?
can be changed into glucose and used in cellular respiration.
Why does a plant need starch?
Glucose is soluble in water and starch is insoluble in water. So for storage in a rather wet medium such as a plant cell, glucose is changed to insoluble starch. When the plant needs glucose for respiration or other processes it changes the starch back to soluble glucose for transportation in solution through the phloem system.
Why is starch a suitable for storing energy?
Starch can be broken down into glucose by an enzyme. Glucose is then used for respiration which provides energy.
Why is starch an indirect measurement of photosynthesis?
Starch is a plants way of storing energy, why it is not a way of measurement as starch levels is determined by how much extra light, once the plant receives enough light it will turn glucose into starch. Starch levels however could be used for the opposite, by measuring starch & glucose you can work out the rate of respiration, just not photosynthesis.
Do enzymes change starch into glucose?
Yes they do. Enzymes change starch into glucose for cellular respiration.

How does eating pasta lead to cellular respiration?
We digest the starch to glucose, which is sent to the cells where it is the fuel for respiration.

Why is the reaction of starch with diastase important in a living system?
Diastase hydrolyses starch into maltose which can then be hydrolysed to glucose - the starting point for ATP production in cellular respiration.
Why is the digestion of starch to glucose necessary?
Starch is a complex carbohydrate therefore it cannot be used and is insoluble unless it is broken down. Also the body requires glucose for important metabolic functions (respiration) to provide energy for the body, starch cannot be used for this process.

What is the monomer of the polymer starch?
If starch is the polymer, then the monomer is glucose, which is a monosaccharide. Starch is a polysaccharide that is made up of glucose molecules.
Where do plants store glucose in?
In plants, glucose is generally stored as starch.
Why does food give the body energy?
It contains some sort of sugar called glucose or starch. When we eat it, the glucose or starch is released. When respiration(sugar+oxygen converted into carbon dioxide+energy+water) occurs, energy is released.
