What happens to the free energy released as electrons are passed from photosystem ii to photosystem i through a series of electr

on carriers? it is used to establish and maintain a proton gradient. it is used to phosphorylate nad+ to nadph. it excites electrons of the reaction center in photosystem i. it is used to synthesize atp through substrate-level phosphorylation?

<span>The correct answer is: It is used to synthesize ATP through substrate-level phosphorylation.</span>  
<span>The free energy released as electrons are passed from photosystem II to photosystem I drive pumping of H+ and building a gradient. H+ flow down their gradient and when they pass through ATP synthase, the ATP is produced by substrate-level phosphorylation (ADP+Pi).</span>

Pretend that you are writing a letter to the president proposing ways that the US can reduce its contribution to climate change.
ahrayia [7]

Answer:

Dear Mr. President,

Your strong voice has called attention to the risks of human-induced climate change and the need to take timely and effective steps to address it. We are pleased to report further progress in our efforts to advise you on climate policy options that could help encourage these steps.

- (Explain what you learned in class today ) I don't know what you were taught in class so you have to figure what to put here.  

Mr. President, our temperatures are consistently rising while moisture is increasingly evaporating. Forest management is merely one piece of the puzzle — something our own firefighters would be quick to remind you. Since 2009, our state has spent more than $130 million on forest health and fire preparedness. These events still overwhelm our residents and resources, because these fires are unlike anything people have seen before.

Sincerely,

Explanation:

hope this helps!

AB+CD (reactant~higher on graph) ---&gt; AC+BD (product~lower on graph)
amid [387]

Answer: Option E) the products have less potential energy than the reactants

Explanation:

Though the actual graph is not displayed, but, whenever reactants occupy a position higher than the product on the graph of reaction coordinate vs time taken, it means the reactants (AB+CD) have molecules with higher energy bonds than the products AC +BD

Thus, the reaction of AB + CD to yield AC+BD will occur spontaneously with the release of energy.

What is the function of the hair follicle​
kaheart [24]

Answer:

A hair follicle anchors each hair into the skin.

Explanation:

The hair bulb forms the base of the hair follicle. In the hair bulb, living cells divide and grow to build the hair shaft. Blood vessels nourish the cells in the hair bulb, and deliver hormones that modify hair growth and structure at different times of life.

For sucrose to be moved from a leaf (source) cell to a root (sink) cell, sucrose is first actively transported into the phloem f
Natali5045456 [20]

Answer:water diffuses into the phloem from the xylem and sucrose moves to the sink

Explanation:Translocation is the movement of ready produced food substances from the site of production to places in the plant where food is needed. such as the roots.the place where food is produced is called the source, the the place where food is used up is called the sink.the leaves are the source in a plant.photsoynthates, which is the plant manufactired food, may move up and down the stem ,majorly to areas of storage and growth.

Surose is the major intermediate product of photosynthesis.it is the form in which sugar is transported.it is conducted by the phloem vessels.this takes place in the long sieve elements that forms the sieve tubes

The high percentage of sucrose in the phloem sap causes water to pass into it from the xylem. This then causes the sap to move from source to sink.

At the sink, sucrose diffuses out of the phloem.it is either stored up or used for growth and repairs
