Answer:

1.protons

2.Down

Explanation:

The ATP Synthase is an enzyme which catalyses the phosphorylation ADP to ATP, for synthesis of ATPs in the matrix of mitochondria and stroma of chloroplast.

                  ADP  + Pi     →     ATPs.

                                 ATPsynthase.

The  source of energy  to power the ATP synthase is from the electrochemical gradient  set up by diffusion of  protons from the intramembrane layer of mitochondria and thylakoid membrane,down   into the matrix or  stroma where the ATPase synthase is located.

The  force for the proton pump  into the intramembrane is   known as the Proton Motive Force.(PMF).it is set up by the electrical mechanisms of electron transport chain. It constantly pumps protons into the intramembrane layers, therefore setting up the electrochemical gradient.

The proton is obtained from the splitting of hydrogen atoms,  carried  by the co-factors NADH+ and FADH2,from the Krebs cycle into the matrix or stroma, into protons and electron.

             H2→→→ H+  + e-.

This explains the ATP synthase activities  for ATP synthesis.

Answer:

The ATP synthase can be thought of as a type of molecule motor that is powered by the flow of __H+_ through the subunits and __down_ their concentration gradient.

Explanation:

There are two steps for the synthesis of carbohydrates in plants; one is light reaction and other is dark reaction. In light reaction the ATP and NADPH are produced from sunlight and these molecules are utilized for combining the carbon molecules in dark reaction.

Before we discuss chemiosmosis (Mechanism of ATP production) we should know that light reaction takes place in the thylakoid membrane of chloroplast. During the light reaction electrons removed from water are excited by light in photosystem I and photosystem II. These excited electron release the energy while traveling down the electron transport chain which is utilized to pump the H+ ions to stroma from lumen. This build a concentration difference of H+ ions across the membrane.

So when these H+ ions flow from stroma to lumen i.e. higher potential to lower potential they passes through ATP synthase complex. ATP synthase produces the ATP by the phosphorylation of ADP that why mechanism is also referred as Photophosphorylation.

Is the blood pressure measured in the calf larger or smaller than the blood pressure measured on the upper arm?
lana66690 [7]
<span>The blood pressure measured in the calf is lower than it is in the arm. Blood pressure in the body is highest right at the ascending arch of the aorta. From that point, the pressure decreases as blood moves "distally" from the heart. Purely mechanically, legs are farther away from the heart than are the arms, thus pressure is less.</span>

Respiration is a process where many chemical bonds inside the body break and release energy. This energy is used to perform vari
dangina [55]

Answer:

The  correct answer is chemical energy from broken bonds is transformed into mechanical energy.

Explanation:

Muscle contraction need energy in form of ATP.ATP contain 2 high energized phosphoanhydride bonds.

                  The hydrolysis of phosphoanhydride bonds releases chemical energy which is transformed into mechanical energy for helping the muscles to move.

svet-max [94.6K]

Answer:

Explanation below

Explanation:

Separation of powers is very important and crucial in federal type of government. This is helpful because it decentralized the power, and prevent one arm of government from being a dominating force.

It will help the government to provide the necessary and needed infrastructure for the citizens. This is because the conclusion will be reached with approval of all the arms of government.

What's the answer to this question
Flauer [41]
The answer is C. Thermal energy is transferred to her face by radiation, and thermal energy is transferred to the bottoms of her feet by conduction. 

Conduction is a method of transferring heat by using the collision of molecules and free electrons (depending on the material). Heat is usually transferred by conduction if both objects are in contact with each other that way the molecules can collide and spread the kinetic energy thus raising their internal heat. So, since the feet and the sand are in contact, so the heat should be transferred by conduction. However, air is a very poor heat conductor, it cannot transfer heat efficiently, therefore, the first answer is not conduction. 

Radiation is a method of transferring heat too but using electromagnetic waves. It works great even in the air, or even with vacuum space. The sun shining from outer space to earth through the vacuum space is also by radiation. So, the first answer is radiation. 

The answer is C, hope it helps!
