11) In C3 photosynthesis, the reactions that require ATP take place in A) the light reactions alone. B) the Calvin cycle alone.
valentinak56 [21]

Answer:

In C3 photosynthesis, the reactions that require ATP take place in

B) the Calvin cycle alone.

Explanation:

In C3 PLANTS PHOTOSYNTHESIS OCCUR IN TWO STEPS-

1. LIGHT stage , WHICH TAKES PLACE IN LIGHT. In this stage water is split and ATP is released.

2. DARK stage, which takes place in dark. This the stage where calvin cycle takes place which require ATP, i.e energy. In this process sugar is produced with help of carbon dioxide. In this carbon dioxide is accepted by 5- carbon molecule ribulose-1, 5-biphosphate, which result into two molecules of 3- phosphoglycerate. this three carbon compound. hence is called as C3 pathway. hence C3 plants.

NADH and FADH2 are both electron carriers that donate their electrons to the electron transport chain. The electrons ultimately
maria [59]

Answer:

Explanation:

NADH and FADH2 are both electron carriers of the electron transport chain. NADH gives up its electrons starting from Complex I, which has a higher energy level compared to other complexes. Energy is given off to pump protons across the membrane by the time electrons are transferred to ComplexIII. More electrons are pumped across the membrane as electrons move to Complex IV. Because NADH commenced giving up its electrons from Complex I (higher energy level complex), more protons are pumped across the membrane gradient, which enables ATP synthase with more power to produce 3ATP molecules per NADH molecule.

On the other hand, 2 molecules of ATP are generated by FADH2 because it starts by giving up its electrons to ComplexII. It missed a chance to pump protons across the membrane when it passed Complex I. By the time the electrons reach Complex IV, less protons have been pumped. The lesser the protons to power ATP synthase, the lesser the ATP molecules produced.

The following picture shows the three primary types of plate boundaries. Which boundary is being shown in label A? an arrow poin
IceJOKER [234]

Answer:

The label A corresponds to Convergent boundary zones  

Explanation:  

When two oceanic plates collide, it occurs oceanic convergence. The thicker and older plate subduces under the other plate, and at this point, it starts the volcanic activity. As the thicker plate descends, it is heated and melted and its materials are incorporated into the mantle. The fast subduction originates magma that ascends to the surface by crevices. This makes place to the formation of grouped <u>volcanic islands</u>, t<u>he island arches</u>. Subduction zones coincide with deep-sea <u>trenches</u> or depressions in the ocean bed. The volcanic islands are arranged in a circumference arch shape, which is bordered by a fossa. Most of these are located in the western Pacific, where the pacific crust is older and thicker, and hence it submerges easier in the mantle.

2.) If you have a prompt and a claim, write your hypothesis down in this form: If ______________, then________________.

3.) Use the scientific process of performing an experiment, like observation, measurement, etc.

4.) LABEL all the sides of your (bar, line, etc) graph.

5.) Write a sentence using your graph in this form:

It (increased/decreased)_________ because _________.

This value is the (greatest/least) __________ because ___________.

6.) Explain why or why not the hypothesis supported your observations and measurements.

My hypothesis (did/didn't) support my experiment because ____________.

7.) In other words, how does your graph, observations, etc., go along with your hypothesis?

Hope this helps.
