The almost pure cellulose obtained from the seed threads of Gossypium (cotton) is tough, fibrous, and completely insoluble in wa

ter. In contrast, glycogen obtained from muscle or liver disperses readily in hot water to make a turbid solution. Despite their markedly different physical properties, both substances are (14)-linked D-glucose polymers of comparable molecular weight. What structural features of these two polysaccharides underlie their different physical properties

Answer:

Cellulose is held by beta 1,4-glycosidic bonds making it linear while Glycogen is held by an alpha 1,4-glycosidic bond making it highly branched.

Explanation:

Cellulose and Glycogen are both carbohydrate polysaccharides formed from glucose monomers. According to the question, cellulose is a tough, fibrous, and insoluble (in water) polymer found to play a structural role in plants' cell wall while Glycogen is another polymer obtained from muscle or liver and disperses readily in hot water to make a turbid solution.

Although these two polysaccharides (cellulose and glycogen) are linked by (1, 4)-glycosidic bonds but the glucose monomers in CELLULOSE are linked by a beta 1,4-glycosidic, hence, making it a straight or linear polymer

GLYCOGEN, on the other hand, is linked by an alpha 1,4-glycosidic bond making it an highly branched polymer. This structure is responsible for the different physical properties of the two molecules.

Ymorist [56]

Answer:

The normal body temperature for humans is 37 degrees Celsius. Most of the enzymes of a human's bodywork best at this temperature. If an enzyme was discovered which works best at 39 degrees Celsius, then it means that the enzyme works at elevated temperatures for events which require slightly higher temperatures.

The enzyme will most probably work for overcoming fever or for reducing the temperature of the body after exercise.

A student draws a fence with several gate as part of a model of cellular transport explain what defence indicates represent blam
Oksi-84 [34.3K]

The given question says that a student has constructed a model of cellular transport using fences and several gates.  

This model can be used to demonstrate the cellular transport.

The gates of the fences can be supposed as the protein pumps and the other fence demonstrates the lipid bilayer.  

Let’s suppose in the fence, there are many cattles, and outside, there are less cattles, but the student open the gate and bring more cattles inside the fence. In this case, the transport of the cattles is similar to the active transport of the molecules using protein pumps. At cellular level, the energy for the active transport is provided by ATP molecules.

Now, let’s say, the student wants to feed the cattles with some nutrition rich food, which can help in maintaining the health of the cattles. The student fills his car with the cattle food and he enters inside the fence through gates. In this case, the food was not present in the fence, but was abundant in the outside environment, so, the diffusion would occur. But food cannot come self, without help of others, so, the movement is facilitated by the car, as it is done by the carrier proteins. Hence, it is an example of facilitated diffusion.

kipiarov [429]

Answer:

The experimenter hypothesized that fertilizer would make the plants grow taller. The results show that, on average, plants with fertilizer grew 0.7 cm taller over the course of 12 days. This small amount of height increase could be attributed to the fertilizer or may be caused by natural differences in the plants.

The rate of O2 production by the light reactions varies with the intensity of light because light is required as the energy sour
kupik [55]

Answer:

The correct answer is option a.

Explanation:

Yes, the light reactions also depend upon the Calvin cycle. Calvin cycle refers to a phenomenon that is used by the plants and algae to convert carbon dioxide from the atmosphere into sugar, the food needed by the autotrophs in order to grow. The plants rely upon the Calvin cycle for food and energy.  

In the given case, the rate of oxygen production would get diminish as the rate of ATP and NADP+ generated by the Calvin cycle diminishes. Of all the outcomes of the Calvin cycle, ADP and NADP+ are the only ones that get utilized by light reactions.  

The ADP and NADP+ are used up by the light reactions to fuel their reactions. This illustrates that if the rate of ADP and NADP+ generated by the Calvin cycle diminishes the production of oxygen by the light reactions also diminishes.
