Answer:
Lacteal is a lymphatic capillary that is found in an intestinal villus.
Explanation:
Lacteal is a type of lympathic capillary and the main function of the structure is to absorb fats that are in the intestinal villi.
The triglycerides which are hydrolyzed by lipase enzyme passes from the lumen of intestine into the enterocytes and re esterified and forms triglycerides.
Lacteal is a part of lymphatic capillary which absorbs and transport those materials that are directly enter through blood stream.
Robert Hooke is the scientist who discovered microscope which helps scientists more in discovering of the cells. During the invention, Hooke carefully controls the height and angle of the microscope he's inventing and also the mechanism of illumination to be make more effective.
Answer:
A. The lytic lifecycle allows viruses to reproduce more quickly but also kills the host and forces the virus to find a new host cell.
Explanation:
The lytic lifestyle of the viruses (e.g. bacteriophage) can be described through the next steps:
- attachment and injection into the host cell (e.g.bacterial cell)
- synthesis of the early virus proteins which break down host's DNA
- virus uses host's machinery (for the replication, transcription and translation) to produce the rest of its proteins and to form new virus particles.
- host cell burst and many new virus particles are released.
During the lysogenic cycle, virus does not kill the host. It integrated its DNA into host's genome and stays dormant until conditions are optimal for reproduction.
Its a large nuclear pore
so pores :)
A new antibiotic is produced that inhibits the synthesis of acetyl-CoA and the electron transport chain in bacteria that normally require oxygen. For each glucose molecule that is metabolized, how many fewer ATP molecules will be produced?
38
4
36
34
2
Answer:
36
Explanation:
Glycolysis of cellular respiration produces only two molecules of ATP per glucose molecule. Kreb's cycle also forms 2 ATP molecules per glucose by substrate-level phosphorylation. However, oxidation of NADH and FADH2 by electron transport chain produces as many as 34 ATP molecules (almost 3 ATP per NADH and 2 ATP per FADH2). This obtains a total of 38 ATP molecules per glucose by the complete pathway of aerobic cellular respiration.
In presence of an antibiotic that inhibits Kreb's cycle and ETC of cellular respiration, a cell would produce only 2 ATP molecules (by glycolysis) per glucose. Therefore, it would obtain 38-2= 36 lesser ATP molecules.
