Answer: The Plant Cell would die

Explanation: Although the Mitochondria is unharmed the Plant Cell still needs the Chloroplasts because they are responsible for Photosynthesis which gives the plant energy, And without the Chloroplast ,Photosynthesis cannot be started

Describe how proteins form (polypeptide)

Natalka [10]

Answer: Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled, conditions became suitable for quarks and electrons to form. Quarks came together to form protons and neutrons, and these particles combined into nuclei.

Humans developed antibiotics to fight bacterial infections. however, some antibiotics are no longer efective in killing the bact

9966 [12]

Evolutionary theory predicted that bacterial resistance would happen. Given time, heredity and variation, any living organisms including the bacteria will evolve when a selective pressure, in this case an antibiotic is introduced. However it also gives doctors an patient some specific strategies for delaying even more widespread evolution of antibiotic resistance; these strategies include; avoid mild doses of antibiotics over long time periods, don't use antibiotics to treat viral infections, when treating bacterial infection with antibiotics, take all the pills, and also using combination of drugs to treat a bacterial infection.

During periods of intense activity, when glycolysis is used in the generation of atp, the reaction lies to the right, decreasing

umka21 [38]

Adenosine monophosphate (AMP) is a regulatory molecule in metabolic processes such as glycolysis and gluconeogenesis. For example, it stimulates the glycolytic enzyme phosphofructokinase, and therefore ATP production, and it inhibits the gluconeogenic enzyme fructose 1,6-bisphosphatase. Adenylate kinase catalyzes the reversible reaction shown here:

2ADP --> ATP + AMP

During periods of intense activity, when glycolysis is used in the generation of ATP, the reaction lies to the right, decreasing [ADP], generating ATP, and accumulating AMP. However, [ATP] is usually much greater than [ADP], and [ADP] is greater than [AMP].

Determine [AMP] when 3% of the ATP in a hypothetical cell is hydrolyzed to ADP.

In this cell, the initial concentration of ATP is 265 ?M, and the total adenine nucleotide concentration (the concentration of ATP, ADP, and AMP) is 368 ?M. The equilibrium constant K is 0.82
