During light reactions, ATP is produced when hydrogen ions move:

Biology
1 answer:
Natalija [7]3 years ago
5 0

Answer:

The correct answer will be option-C.

Explanation:

Light-dependent reactions are the reaction of photosynthesis which takes place in the presence of light.

During light reaction, ATP and NADPH intermediates are produced which are utilized during the light-independent reaction. The main reactions that take place during light reactions are photolysis of water and ATP synthesis due to the electron transport chain.

Electron transport chain generates electrochemical gradient across the thylakoid membrane sue to the accumulation of protons in the thylakoid lumen and fewer protons in the stroma of the chloroplast.

This causes the osmotic movement of protons down their concentration gradient through ATP synthase. The movement if hydrogen ions take place from thylakoid lumen to stroma forming ATP molecules.

Thus, Option-C is the correct answer.

Which of these statements can be predicted with the help of science
forsale [732]

Answer:

Something that can be tested, or rationalized.

Explanation:

You didn't give any statements to choose from, so I'll give you a rule of thumb. When finding a scientific statement, make sure it's something like "The tide is higher at noon than it was at 3 am." and not "Your dog is itchy, so that means a bad storm will arrive."

Is neon different from oxygen?And how is it different? Please explain.
EleoNora [17]

Neon is a member of the noble gas family. Other elements in this family includes <span>helium, argon, krypton, xenon, </span>and <span>radon. </span>These gases are in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The noble gases are sometimes called the inert gases. This name comes from the fact that these elements do not react very readily. In fact, compounds exist for only three noble gases—krypton, radon, and xenon. Chemists have yet to prepare compounds of helium, neon, or argon.

Neon was discovered in 1898 by British chemists William Ramsay (1852-1916) and Morris Travers (1872-1961). It occurs naturally in the atmosphere, but only in very small amounts.

According to the envelope in Model 1, who is supposed to receive the letter?
matrenka [14]

If you are referring to the model attached, then the answer would be:

<u><em>Jane Doe</em></u>

This model demonstrates how one can categorize something based on certain information from general to specific characteristics. For example, many people have the same names, so how would we know who the person is referring to? Using specific details like the house number, building name or apartment, street and zip code will help narrow down who the letter is addressed to specifically. This is a method they use to organize organisms into specific classifications, based on specific characteristics.

The plasma membrane represents an energetic barrier to the free diffusion of ions from the extracellular space into the cytoplas
Marysya12 [62]

Answer:

Why are molecules such as valinomycin effective at transporting ions across the membrane?

Valinomycin is effective as transporting ions across the membrane because it is no charged, so it can carry ions.

Why would a drop in temperature to or below the transition temperature limit valinomycin mediated K+ transport across the plasma membrane?

Valinomycin is limited by temperature because its activity is highly sensitive and it depends on a stable and an average temperature.

Explanation:

Valinomycin is effective at transporting ion across the membrane because is an antibiotic that alternates hydroxy and amino acid, ans it helps membranes to be permeable. Valinomycin is a cyclic molecule that helps in ions transportation through membranes. Also, antibiotics have a temperature range of activity, that's why it is sensitive to changes.
