Atp synthesis in chloroplasts is very similar to that in mitochondria: electron transport is coupled to the formation of a proto

n (h ) gradient across a membrane. the energy in this proton gradient is then used to power atp synthesis. two types of processes that contribute to the formation of the proton gradient are:

Answer:

a. processes that release H+ from compounds that contain hydrogen, and

b. processes that transport H+ across the thylakoid membrane.

Explanation:

ATP synthesis can be defined as the process where ATP is produced from the transfer of electrons from membrane to the matrix of the cells. When ATP is synthesized, it is used as a source of energy in the at organism.

ATP is synthesized in plants using the enzyme ATP synthase that is found in the chloroplasts during the process of photosynthesis.

Electron transport is joined to the formation of a proton (h ) gradient by processes that release H+ from compounds that contain hydrogen, and processes that transport H+ across the thylakoid membrane across the membrane. The energy present in this proton gradient is then used to start up the process of synthesizing ATP.

In a hypothetical situation, a bacterium lives on the surface of a leaf, where it obtains nutrition from the leaf's nonliving, w
Rashid [163]

Answer:

The correct ecological sequence regarding this case, to answer your question: What is the correct sequence of ecological roles played by the bacterium in the situation decribed here, would be: 1. mutualism, 2. Parasitism and finally 3. Nutrient recycler.

Explanation:

Ecological balance comes when species interact, and help each other out, by carrying out tasks that the other species cannot perform. When this happens, both species benefit from the presence of the other, and thus are kept in balance. However, conditions may change that will affect this balance.

In this case, we have a bacteria and a plant that are ecologically balanced with each other: the plant provides nutrients to the bacteria, and the bacteria helps the plant by maintaining other microorganisms away. However, when the conditions of the plant change, giving the bacteria access to its insides, which are more nutrient-rich, than the outside, these bacteria do not waste time and infect the plant, until it kills, and then decomposes, the plant. Given the sequence, the first part is known as mutualism: to species sharing benefits. Parsitism, because the bacteria infected the plant and lived now off it, destroying it. And finally, nutrient recycler because the bacteria breaks down the plant, decomposes it, returning to the ecosystem nutrients that were inside the plant.

Write a three paragraph essay on cellular respiration.Each paragraph should cover one step,in order.Each paragraph should be 3-5
inna [77]

Answer:

Cellular Respiration

As you all know, cellular respiration is one of the, if not the, most important process that goes on in our bodies and other animals' bodies today. Cellular respiration is the process that is opposite from photosynthesis. While plants are taking in carbon dioxide and water to make sugar and oxygen, cellular respiration uses the oxygen and sugar o make carbon dioxide, water and 36 ATP. The three "mini processes" that take place during cellular respiration are glycolysis, oxidative respiration, and the electron transport chain. Fermentation also occurs in some cases where there is no oxygen present.

Glycolysis is the first stage in cellular respiration. It starts with a six-carbon glucose. Then, two ATP come and are converted to two ADP and two phosphates. Those same phosphates are added to the glucose to make a six-carbon glucose phosphate. That is then divided into two 3-carbon sugar phosphates. ADP comes and leaves charged as ATP because of the phosphate. Without the phosphates the process finishes with two 3-carbon piruvates.

If there is no oxygen present after glycolysis, then the next process is fermentation. Fermentation takes the 3-carbon piruvates from glycolysis and adds and electron to them. The result is lactic acid in animals and ethyl alcohol and carbon dioxide from plants, yeast and fungi. Oxygen can then be added back to the lactic acid to form piruvate again.

After glycolysis or after the oxygen is added back to lactic acid from fermentation, the oxidative respiration, also known as the Krebs cycle, takes place. The 3-carbon piruvates are converted to acetyl-CoA. That is then turned into a 6-carbon citrate. After an electron is added to NAD+ to turn it into NADH, a 5-carbon molecule is formed. Then it turns into a 4-carbon molecule which is then recycled.

The electron transport chain is occurring the whole time that cellular respiration is taking place. It starts with a NADH and a FADH2. Electrons and hydrogen ions are added until the final results are NAD and 2H which yields 32ATP and turns O2 into H2O.

Over all there is 2ATP made during glycolysis, 2ATP made during Krebs cycle, and 32ATP made during the electron transport chain for a grand total of 36ATP!!! After all these products are made they are then converted back by photosynthesis and the cycle goes on and on and on.

Create a “why” type of questions that relate to the interactions of the four subsystem of the earth.
guajiro [1.7K]

1. Why hydrosphere is important for the living organisms?

2. Why atmosphere is important for the living organisms?

3. Why lithosphere is important for the living organisms?

4. Why biosphere is important for the living organisms?

These are the four questions related to the subsystem of the earth. There are four subsystem of the earth named "lithosphere" which means the land, "hydrosphere" which means water, "biosphere" which means living things and "atmosphere" which means air.

All these subsystems are important for the survival of living creatures on the planet earth because all living organisms depends on these four subsystem.
