Answer: The true statements about protein digestion and hydrolysis are;
1. Hydrochloric acid in gastric juices cause protein denaturation.
2. In small intestine trypsin attacks peptide bonds.
3.free amino acids are absorbed by the intestinal wall.
Explanation:
Protein digestion occurs in the duodenum and stomach and it is the breakdown of proteins to amino acids by action of Enzymes like trypsin, pepsin.
Protein is digested by the hydrolysis of carbon-nitrogen bond. Mechanical digestion of protein begins in the mouth and it continues in the small intestine and stomach.
Chemical digestion starts in the stomach where by hydrochloric acid in the gastric juice denatures the protein and convert pepsinogen to pepsin enzyme which convert the protein in food to peptides. Trypsin attacks the peptide bond that involves the carboxyl group which breaks it to polypeptide. Exopepdisases and dipeptidases breaks it down to amino acids. The amino acids released by protein digestion is then absorbed by the intestinal wall
Answer:
C. Slide A, plant cells; Slide B, animal cells
Explanation:
The slide A has some organelles that are unique to plant cells, and are mostly found in plant cells. Organelles such as a cell wall and chloroplasts are unique features of plant cells. They are normally absent in animal cells.
Therefore, slide A, which has these cell organelles can be rightly labelled as "plant cells", while side B, which has these organelles missing, can be labelled as "animal cells".
The term myoparesis is used to describe the weakness or slight paralysis of the muscles. The myoparesis can begin in a person suddenly or it might progress with gradual weakness of the muscles. The affected individual may suffer from weakness of the muscles with incomplete paralysis along with experiencing pain and spasms in the affected muscles. The causes for the development of myoparesis includes stroke, cerebral palsy, multiple sclerosis, and spinal cord injury.
Hence, the answer is 'weakness or slight muscular paralysis'.
Answer:
C. Initially, the mouse and human proteins were confined to their own halves of the newly formed hybrid cell, but over time, the two sets of proteins became evenly intermixed over the entire cell surface. This suggests that proteins, like lipids, can move freely within the plane of the bilayer.
Explanation:
Due to the fact that a membrane is a two-dimensional fluid, a lot of its proteins, as it is seem in lipids, can flow without obstruction in the plane of the bilayer. This lateral diffusion was at first illustrated by analysing the fusion of a mouse cell to a human cell to produce a big, hybrid cell and then follow up the dispersion of specific mouse and human plasma membrane proteins. In the start up, the mouse and human proteins are restricted to their respective halves of the just produced hybrid cell, but in the space of half an hour or so, the two groups of proteins are noticed to be equally combined over the whole cell surface.
Answer: The difference between the high tide and low tide.
The tidal range is the difference in height of high and low tides. The tides may rise or fall in the ocean due to the effect of gravitational force exerted by the Moon and the Sun and because of the earth rotation. Tidal range is not a constant parameter but it changes with respect to the locations of the Moon and the Sun.
