<span>The reaction
that takes place in the stroma is collectively known as the Calvin Cycle. The
stroma is responsible for the 2nd stage of photosynthesis where ATP
and NADPH are used to capture and reduce carbon dioxide in the plant cell.</span>
<span>
It is a fluid-like organelle that surrounds the grana within the
chloroplast in plant cells. The stroma is also responsible for storing
chloroplast DNA and chloroplast ribosomes where molecular processes like
replication and transcription/translation of chloroplast proteins occur.</span>
Answer:
The monitoring the growth rate of E.Coli bacteria is a useful indicator of the effect of glycotic enzyme mutation on the bacteria as the flow of intracellular metabolic components depends on the availability of carbon. Hence the change in carbon source can change the glyclyotic enzyme mutation up or down.
Explanation:
Continuous culture is a method that can be used by the researchers for determining whether mutation affects the growth rate of E.Colin-M bacteria
If the growth medium contains higher concentration of acetate,then the growth of the bacteria will be inhibited without inhibiting its central metabolism.
When E.Coli grows ,it secrets acetate. This mechanism is called overflow mechanism. Regulatory interactions mediated by acetyl-phosphate plays a major role in inhibiting growth by acetate. The uncoupling effect of organic acids or perturbation of the anion composition of the cell is a major reason for growth inhibition.
Answer:
Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50,000 years, and most rocks of interest are older than that
Explanation:
Diffusion is essential for cells to bring nutrients and releasing wastes WITHOUT spending energy. This is accomplished by the "urge" of a system to achieve equilibrium, which means that materials tend to flow from high concentration to low concentration area. For example, if a cell lacks amino acids, and therefore has a low concentration of it inside the cell compared to the outside, then by diffusion, the amino acids outside will flow in through the membrane until the concentrations of amino acids outside and inside the cell are the same. All these are done without spending energy from the cell. Note, however, that simple diffusion cannot transport larger particles or those insoluble in lipids; these materials have to be transported with facilitated diffusion, where a carrier on the membrane of the cell will help bring in the materials.
<span>Diffusion is when particles in a more concentrated area move to a less concentrated area, through a semi- permeable membrane. Without diffusion, the cells in your body will not be able to obtain the resources they need to survive, like water and proteins.</span>
