State where bile is synthesized and explain the role of bile in digestion and excretion

1 answer:

3 0

Liver secretes bile which is then stored in gall bladder. Bile enters the duodenum via the bile duct. Bile emulsifies lipids, transforming large lumps of lipids into tiny droplets, which provide a larger surface area for digestion. This allow lipid digestion to proceed more rapidly. Bile contains bile acids, which are critical for digestion and absorption of fats and fat-soluble vitamins in the small intestine.Many waste products, including bilirubin, are eliminated from the body by secretion into bile and elimination in feces.

Be able to compare/contrast humoral immunity with cellular immunity.

aksik [14]

Solution:

The difference between them are:

The humoral system of immunity is also called the antibody-mediated system because of its use of specific immune-system structures called antibodies. The first stage in the humoral pathway of immunity is the ingestion (phagocytosis) of foreign matter by special blood cells called macrophages. The macrophages digest the infectious agent and then display some of its components on their surfaces. Cells called helper-T cells recognize this presentation, activate their immune response, and multiply rapidly. While,

The cell-mediated immune response involves cytotoxic T-cells, or killer-T cells. Body cells that have been infected by foreign matter often present components of that material on their surfaces. Killer-T cells recognize these displays and respond by ingesting or otherwise destroying the infected cell. Killer-T cells are also important in the body's defenses against parasites, fungi, protozoans, and other larger cells that might have found their way into the body. The killer-T cells recognize these large invaders by their foreign proteins and then destroy them.

Part 1: crossing beak color and tail-feather length cross a yyll (heterozygous parent with dominant traits) with yyll (homozygou

Luba_88 [7]

Since you forgot to put capital letters i assume it's like this:

1)A Cross between YyLl (heterozygous parent with dominant traits) and yyll (homozygous parent with recessive traits).

 2)offspring YyLl: 400, Yyll: 100, yyLl: 100 and yyll: 400

The recombinant offspring are allele combinations that are not directly inherited from the parents.
The parents combinations:YyLl and yyll,
The recombinant combinations: Yyll and yyLl
The other types are exacly like the parents so they are not recombinant.

answer: Yyll and yyLl

2. In the citric acid cycle, malate is oxidized to oxaloacetate by the enzyme malate dehydrogenase, which uses NAD+ as an electr

atroni [7]

Answer:

NAD+ act both as coenzyme as well as electron acceptor compound and get reduced to NADH by accepting electron.

Explanation:

NAD+ act as co enzyme of various biological catalyst such as malate dehydrogenase, isocitrate dehydrogenase etc.

NAD+ can act as co enzyme only in its oxidized form but not in its reduced form called NADH.

Many reaction needs NAD+ to occur such as conversion of glyceraldehyde 3 phosphate to 1,3 bisphosphoglycerate, malate to oxaloacetate.

That"s why NAD+/NADH ratio is kept very high because if this ratio bychance get low then it will hamper the normal redox potential of NAD+/NADH.As a result many biochemical reaction will not take place.
