<h2>Monosaccharides</h2>
Explanation:
Monosaccharides are the simplest form of sugars found in innumerable common food items such as honey, cane sugar, fruits
Monosaccharides are divided into two groups depending on the presence of functional groups,if aldehyde group is present then it is known aldoses and if ketone group is present then it is known as ketoses
On the basis of carbon atoms they can be classified as: triose(3),tetrose(4),pentose(5),hexose(6) and so on
a. erythrose : tetrose ketose-It is not correctly paired because erythrose is a tetrose monosaccharide which has one aldehyde group hence is an aldose
b. dihydroxyacetone : triose ketose-It is correctly paired;it is an aldose-ketose pair
c. erythrulose : tetrose aldose-It is not correctly paired because erythrulose is a tetrose monosaccharide having ketone as functional group hence is a ketose
d. fructose : hexose ketose-it is correctly paired;It is an anomer because in D-fructose carbonyl group is at C-2 hence C-2 is the anomeric carbon
e. ribose : hexose aldose-it is not correctly paired because ribose is an aldo pentose not hexose;ribose is an aldo-ketose pair
f. glyceraldehyde : triose aldose-it is correctly paired;an aldo group
The answer is C, hope this helps
The surface layer of the water freezes solid creating a barrier that insulates the ice below so that it keeps a steady temperature usually a few degrees above freezing (32 degrees).
Answer:
Nutrients support vital functions, including growth, the immune, the central nervous system, and preventing disease.
Explanation:
Answer:
1.Plasma membrane
The plasma membrane surrounds the cell to create a barrier between the cytosol and the extracellular matrix. Plasma membranes also enclose lumens of some cellular organelles.
2.Endoplasmic reticulum
The endoplasmic reticulum (ER) is a large network of membranes responsible for the production of proteins, metabolism and transportation of lipids, and detoxification of poisons. There are two types of endoplasmic reticulum with separate functions: smooth endoplasmic reticulum and rough endoplasmic reticulum. The presence or absence of ribosomes in the ER’s plasma membrane determines whether it is classified as smooth or rough ER.
3.Golgi apparatus
The Golgi apparatus appears as a series of flattened, membranous sacs, or cisternae, that resemble a stack of pancakes just off the rough endoplasmic reticulum. It receives vesicles containing proteins recently produced by the rER. The Golgi apparatus can be compared to a warehouse or post office for newly formed proteins. Here the proteins are further modified, packaged, and sent off to their final destinations in the cell or body.
