A diseased cell is no longer able to produce proteins. Which cell structure is most likely malfunctioning?

Biology
1 answer:
IRINA_888 [86]3 years ago
4 0

Answer:

The ribosomes

Explanation:

Ribosomes are the organelle that produce proteins within eukaryotic and prokaryotic cells- taking information from the DNA in order to produce proteins.

Other organelles may be held responsible for the lack of protein production, but in this case it is most likely the ribosome.

Which of these is not part of insect immunity? A. enzyme activation of pathogen-killing chemicals B. activation of natural kille
Firlakuza [10]

Insect immunity doesn't include the property of an enzyme activation of pathogen-killing chemicals.

What is enzyme activation of pathogen?

Due to various trehalose's importance in pathogenic organisms, there has lately been a surge of interest in trehalose metabolism for therapeutic applications.

  • TPP (trehalose-6-phosphate phosphatase) is an important enzyme in the most important biosynthetic pathway (OtsAB).
  • The enzyme properties of recombinant TPPs from five key nematode and bacterial pathogens, including three new members of this protein family, are compared here.
  • The kinetics of trehalose-6-phosphate hydrolysis demonstrate that all five enzymes exhibit burst-like kinetic behaviour, defined by a drop in enzymatic rate beyond the pre-steady state.
  • Multiple global conformational changes in members of this enzyme family during substrate processing can explain the observed super-stoichiometric burst amplitudes.

Hence, the correct answer is option A

What major structure brings oxygen and nutrients to the cells and carries away waste?
liubo4ka [24]
<span>The major structure that supplies the cells with nutrients and removes their waste is the circulatory system. The circulatory system is composed of the heart, the blood vessels going from and back to the heart, and the blood that travels inside them. The blood vessels that carry nutrient and oxygen-rich blood to the cells are arteries. They become the thinner arterioles, and then the thinnest capillaries. With the exception of the pulmonary arteries, which carry non-oxygenated blood from the heart to the lungs, all arteries carry oxygenated blood. The capillaries disburse the nutrients and oxygen to the cells and pick up wastes and carbon dioxide, form into the thicker venules, then to form veins, which lead back to the heart (with the exception of the pulmonary veins, which carry oxygenated blood from the lungs to the heart). Veins also differ from arteries in that veins have valves to prevent blood from flowing backward.</span>

How many grams of CaCl2 are in 0.75M solution with a volume of 1L
grandymaker [24]

83.235 grams of CaCl2 is required to make 1 litre of 0.75M solution.

Explanation:

Molarity or molar concentration is the number of moles of solute that can be dissolved in 1 L of a solution.

let us find the number of moles

n=C*V                Concentration is 0.75M

                          Volume is 1000ml.

n= 0.75*1

n= 0.75

This means there are 0.75 moles of CaCl2 in 1000 ml of solution of .75M.

Molar mass of CaCl2 is = 40.08+ 2(35.5)

                                       =   110.98 gms

Thus 1 MOLE OF CaCl2 weighs 110.98

         so 0.75 moles will weigh  110.98*0.75

                                              =  83.235 grams of CaCl2 is required to make 1 litre of 0.75M solution.
