why do polysaccharides like cellulose and peptidoglycan able to resist degradation and enzymatic activity

Biology

Polysaccharides like Cellulose form insoluble micro-fibrils making it resistant to degradation and enzymatic activity.

<u>EXPLANATION: </u>

  • Polysaccharides components in general broken down monosaccharides and they are very little enough to be absorbed by the body.
  • But the polysaccharide like cellulose cannot be absorbed by our body.
  • Cellulose is made up of simple polymers that form insoluble micro-fibrils results in resistant to degradation and enzymatic activity.
  • Also, molecules of each micro-fibril are so tightly packed structure and prevent the penetration of enzymes.
  • Thus, cellulose degradation requires a complex enzyme and cellulose.

Bond [772]
<span>The correct answer is 6.</span>  
<span>
When we compare male and female, the prevalence of osteoporosis and the rate of fractures are much higher in postmenopausal women than in men of the same age.  Because of that, this condition is often called “woman’s disease”. One of the explications is that women have smaller and thinner bones than men. Also, estrogen decreases when women reach menopause, which can cause bone loss.</span>

Cellular respiration map
nexus9112 [7]

Explanation:

Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate          (through the process of glycolysis in the cytoplasm).

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

Further Explanation:

In all eukaryotic cells, mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced.

Oxidative phosphorylation follows; this is a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

  • Glycolysis: occurs in the cytoplasm. 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
  • The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
  • The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

In which situation would new technology be most likely to cause a change in an existing theory about new structures a cell?
marysya [2.9K]

The new technology allows detection of a structure that could not be detected previously. Thus, the correct option is D.

<h3>What are the benefits of technology?</h3>

Sales will probably improve as a result of technology that makes it simpler for people to buy from you, including an e-commerce solution and numerous payment apps. Marketing departments are forced to adapt the social media platforms that your clients and potential customers use since they are born and die on a monthly basis.

The tasks that HR departments perform for hiring, reviewing applicants, onboarding, and training involve a significant amount of technology. The more HR duties you can complete using technology, the quicker they can be completed and the less likely it is that you will make a mistake that could result in a lost recruit, an employee leaving, or a lawsuit. Employee education on topics like benefit enrollment and corporate policies, for instance, guarantees appropriate paperwork is done and cuts down on training time for new hires.
