Which of the following are carbohydrates?
Alpha glucose
Starch
Cellulose
Beta glucose
Glycogen
Which of the following is also known as 'animal starch'?
Which of the following are polysaccharides?
Which of the following is the monosaccharide found in starch?
Which of the following has a structural function?
Which of the following can be hydrolysed?
Which of the following are found in plants?
Which of the following stains deep blue with iodine solution?
Which of the following is found in the form of grains?
Glycogen is more highly branched than starch. True or False?
True
False
Which of the following is wound into a tight coil?
Which of the following is stored mainly in muscle and liver?
Starch is insoluble, why is this an advantage?
It doesn't diffuse easily out of cells
It doesn't draw water into the cells via osmosis
It can draw water into the cell via osmosis
Which of the following easily diffuse in and out of cells?
Which of the following is made up of beta glucose monomers?
Where is starch found in large amounts?
Seeds
Storage organs
Hay
Starch is not an important component of food. True or False?
Which of the following has branched chains?
Which of the following has hydrogen bonds between adjacent chains?
Which of the following is never found in plant cells?
Glycogen has a similar structure to cellulose. True or False?
Which of the following contains molecules rotated through 180 degrees?
Starch is formed in a condensation reaction and is linked by glycosidic bonds. True or False?
Cellulose is strong due to the individual strength of each hydrogen bond within it. True or False?
How is starch suited for energy storage?
Starch is insoluble therefore it doesn't diffuse out of cells or draw water into cells
Starch is compact so a lot can be stored in a small space
When hydrolysed, starch forms alpha glucose which is easily transported and readily used in respiration
Starch is insoluble so is able to diffuse out of cells, and draw water into cells
Starch can't be hydrolysed
Starch is compact so not a lot can be stored in a large space
Cellulose is a major component of cell walls, providing rigidity and therefore preventing the cell bursting via osmosis. How?
Cellulose exerts an outward pressure on the cell wall which prevents any further influx of water
Cellulose exerts an inward pressure on the cell wall which prevents any further influx of water
Glycogen is insoluble. Is this an advantage or disadvantage?
An Advantage
A Disadvantage
Due to cellulose, cell walls in plant cells are so rigid and turgid that they push against one another, making harbaceous plants...
...semi rigid maintaining its turgid state. This provides maximum surface area for photosynthesis
...fully rigid maintaining its turgid state. This provides maximum surface area for photosynthesis
