Proteoglycans are part of the extracellular matrix; they provide structure, viscosity and lubrication, and adhesiveness. They are composed of proteins conjugated to carbohydrate components called glycosaminoglycans. The glycosaminoglycan component makes up the majority of the mass of a proteoglycan. Which of these are possible components of glycosaminoglycans

Answers

Answer 1

Answer:

This question lacks options, options are:  a. beta-D-fructofuranose b. amylose c. uronic acid d. N- acetylglucosamine. The correct answers are c and d.

Explanation:

Glycosaminoglycans are very long, unbranched polysaccharides, made up of repeating units of disaccharides. One of the disaccharides is always an amino sugar, which can be N- acetylglucosamine. The other is uronic acid (it can be iduronic acid or glucuronic acid and is often sulfated at position 2). The amino sugar is usually sulfated and the rest of the sugars have carboxyl groups, which give the structure a negative charge, which attracts a large amount of cations such as sodium. Glycosaminoglycans are often covalently bound to proteins to form proteoglycans. Hyaluronic acid is the only glycosaminoglycan that does not form protein bonds and does not have sulfate groups in its structure.

B) The blood absorbs the nutrients that the digestive system obtains from food the two organ systems work together to deliver nutrients to cells.

The circulatory system and digestive system both are working to deliver food to each and every cell.

How do organ structures get meals to the cells?

The digestive system converts the ingredients we consume into their simplest bureaucracy, like glucose (sugars), amino acids (that make up protein), or fatty acids (that makeup fat). The damaged-down meals are then absorbed into the bloodstream from the small intestine and the nutrients are carried to every mobile in the body.

These frame structures are all characteristic to maintain the cells in your frame: the circulatory, respiration, and digestive structures provide the nutrients and electricity your cells need to stay. The immune gadget protects these cells from pathogens.Your circulatory gadget, which consists of your coronary heart, blood, and blood vessels, is liable for transporting vitamins to the cells of your body. Particularly, nutrients are transported at some stage in your frame thru your blood thru capillaries, tiny blood vessels that join arteries to veins.

The cell consists of three components: the cell membrane, the nucleus, and, between the 2, the cytoplasm. In the cytoplasm lie complicated arrangements of first-class fibers and loads or maybe hundreds of minuscule but awesome structures known as organelles.

A. The results are close to a 1:1 ratio of plants with red flowers to plants with white flowers. Therefore, the genotypes of the parents are Rr and rr.
B. The results should yield plants with red flowers and plants with white flowers in a 3:1 ratio due, so the geneotype of each parent is Rr. The number of offspring was not large enough to produce the expected results.
C. The results differ from the predicted values. Therefore, the genotypes of the parents cannot be determined.

Explanation:

If green plant cells are incubated in the presence of CO2 molecules containing radioactive carbon atoms, the fate of the carbon atoms can be followed. In an experiment, radioactive CO2 was given for 1 minute to plant cells, and then the cells were examined after 1, 5, 10, 20, and 30 minutes. The following molecules were labeled with radioactive carbon at some point(s): glucose, glyceralde-hyde 3-phosphate, glycine (an amino acid), 3-phospho-glycerate, ribulose 1,5-bisphosphate, and sucrose.

Required:
List these molecules in the order in which they first become labeled.

Answers

Answer:

GlycineRibulose 1,5-bisphosphate3-phosphoglycerateGlyceraldehyde 3-phosphate.GlucoseSucrose

Explanation:

The glycine, among other amino acids, helps to improve chlorophyll production and promotes the process of photosynthesis.  

Calvin cycle

During the carbon fixation phase, a CO² molecule combinate with a ribulose 1,5-bisphosphate to form 6-carbonated molecules, which will divide into two 3-phosphoglycerate molecules.  

During the reduction phase, NADPH donates its electrons to reduce 3-phosphoglycerate molecules, and turn them into glyceraldehyde 3-phosphate.

During the regeneration phase, a glyceraldehyde 3-phosphate molecule leaves the cycle and goes to the cytosol to form glucose. This step can be done when three CO² enter the cycle and produce six glyceraldehyde 3-phosphate molecules. One of them leaves the cycle to form glucose, while the other five are recycled.

Cytosol:

Once in the cytosol, glyceraldehyde 3-phosphate molecules are used to form glucose and fructose. These two molecules are the monosaccharides that form the sucrose.

Once sucrose is formed, it is transported from the photosynthetic tissues to different parts of the plant by the phloem.

Which of the following is NOT involved in photosynthesis or cellular respiration?
a
cytokinins
b
chlorophyll
c
carbon dioxide
d
water

Answers

Answer:

a

Explanation:

Cytokinins are not involved in photosynthesis or cellular respiration. They are plant hormones that help regulate cell division and growth. On the other hand, chlorophyll, carbon dioxide, and water are all involved in photosynthesis and/or cellular respiration. The correct option is A.

What are Cytokinins?

Cytokinins are plant growth hormones that stimulate cell division and delay senescence. They play a role in plant growth and development, but they are not involved in photosynthesis or cellular respiration. On the other hand, chlorophyll, carbon dioxide, and water are all involved in photosynthesis.

Chlorophyll is a pigment that absorbs light energy and converts it into chemical energy, while carbon dioxide and water are used to make glucose and oxygen through the process of photosynthesis.

Cellular respiration is the process by which cells convert glucose and oxygen into energy. Both carbon dioxide and water are produced as byproducts of cellular respiration. Therefore, all the options except cytokinins are involved in either photosynthesis or cellular respiration.

Therefore, the correct option is A.

Geology- approximately how much more energy is released in a 7.5 richter magnitudue earthquake than a 5.5?

Answers

Answer:

About 2000 thousand times more

Explanation:

The amount of energy released in a 7.5 richter magnitudue earthquake than a 5.5 is 4,462,369,085,588,121 Joules greater than 5.5 scale.

What is the Richter magnitude scale?

The Richter scale or the Richter magnitude scale is a measure of the strength of earthquakes, which are developed by Charles Francis Richter and was presented in his landmark 1935 review paper, where he called it the magnitude scale. This paper was later revised and renamed as the local magnitude scale, which is denoted as ML .

The Richter magnitude of an earthquake can be determined from the logarithm of the amplitude of waves which are recorded by seismographs.

The energy of the earthquake with magnitude 5.5 is 4,466,835,921,510 J and with magnitude 7.5 is 4,466,835,921,509,631 J.
