Answer:
On the exterior of the cell.
Explanation:
The black spots as mentioned in the given case would appear on the exterior of the cell after three hours, which suggests that the proteins or the enzymes had been discharged from the pancreatic cell. The mentioned method of labeling and then chasing the component is known as a pulse-chase experiment.
In this experiment, the labeled compounds are used to follow the dynamics of cellular pathways and procedures. The molecules in a cell get produced and degraded spontaneously at various rates. These changes in the localization of the molecule and its expression levels with time can be determined by exposing or pulsing cells to a labeled compound.
After this the cells are exposed sequentially to the same compound unlabeled, the process is termed as the chase. The compounds are generally labeled with fluorescent dyes or radioisotopes.
Answer:
The correct answer is : C .It will decrease ATP production because fewer protons will be able flow down through ATP synthase.
Explanation:
- Oxidative Phosphorylation is a process which involves two steps:
- Transport of electrons from the reduced compounds like NADH (Nicotinamide adenine dinucleotide hydrogen) and FADH₂ (Flavin adenine dinucleotide dihydrogen) through the electron transport complexes, located in the inner mitochondrial membrane, to oxygen for the generation of water molecules.
- Synthesis of ATP or adenosine triphosphate from ADP or adenosine diphosphate and inorganic phosphate by an enzyme called ATP synthase which is located in the inner mitochondrial membrane. This enzyme harnesses energy by carrying protons from the inter-membrane space into the mitochondrial matrix and in the process produces ATP.
- Oxidative phosphorylation takes place in the mitochondria, especially involving the inter membrane space, inner membrane and mitochondrial matrix
- During the transport of electrons through the protein complexes (I, II, III, IV) of the electron transport chain a proton gradient is generated across the inner mitochondrial membrane.
- The proton gradient is such that the concentration of protons is more in the inter-membrane space and less in the matrix of the mitochondria.
- This proton gradient provides the energy to the ATP synthase for the synthesis of ATP.
- Dinitrophenol is responsible for making the inner mitochondrial membrane permeable to protons. As a result protons can directly diffuse through the inner mitochondrial membrane from the inter-membrane space into the mitochondrial matrix equalising the concentration of protons across the inner mitochondrial membrane. This causes distortion in the proton gradient. Hence, protons are no longer available for the ATP synthase to operate and synthesise ATP.
The statement that describes this prediction is as follows:
- The prediction is useful because it explains what observations will be made if a hypothesis is true.
Thus, the correct option is D.
<h3>What is Herbicide?</h3>
Herbicide may be defined as a chemical agent that is responsible for destroying or inhibiting the growth of a particular plant as compared to the normal one.
The projection is necessary because it supports the product after a one-year duration. So for example, if after one year there is undoubtedly a reduction in the intermediate height of the tomato plants, then we can absolutely say that it is because of the existence of NoGro herbicide which is supplied in water.
Therefore, it is well described above.

<span>Here are some of the factors that a nurse should consider when administering a medication to a pediatric client verses and adult client. As part of core drug knowledge the nurse should consider age, weight, height also previous and current medical conditions.</span>
Answer:
The correct answer would be -
Remains the same: proton pumping rate, electron transport rate, rate of oxygen uptake.
Decreases or goes to zero: rate of ATP synthesis, size of protein gradient
Explanation:
An H+ channel forms and the membrane becomes very permeable to protons if the protein gramicidin is integrated into a membrane. If gramicidin is added to an actively respiring muscle cell, it will affect the in the following manner:
Remains the same:
proton pumping rate, electron transport rate, rate of oxygen uptake.
Decreases:
rate of ATP synthesis, size of protein gradient
None of these will show an increase due to the addition of gramicidin tlo actively respiring muscle cells.
