The set of proteins in the cristae of the mitochondrion, which collectively extract the energy from reduced coenzymes to form atp, are called the.
Cell respiration involves different steps, among which there is the oxidative phosphorilation that produces and stores ATP. The answer is the electron transporter chain.
ELECTRON TRANSPORTER CHAIN -oxidative phosphorylation-
The electron transporter chain + chemiosmosis constitute the process of oxidative phosphorylation.
Chemiosmosis
Chemiosmosis refers to ATP production through a proton gradient.
Electron transporter chain
The electron transporter chain is a series of molecules and proteins located in the internal mitochondrial membrane.
It constitutes a series of enzymatic reactions to release and save energy for the correct functioning of the organism.
Along the chain, there are four proteinic complexes in the membrane, I, II, III, and IV, that contain the electrons transporters and the enzymes necessary to catalyze the electrons' transference from one complex to the other.
Different redox reactions occur to pass electrons along the chain.
Released energy creates a proton concentration gradient used to synthesize ATP.
Steps in the electectron transporter chain1) NADH provides electrons to the first complex, Complex I. From there, electrons go to the coenzyme Q that carries them to complex II. Meanwhile, complex I pomp four protons to the intermembrane space.
2) Complex II receives electrons from CoQ and also receives electrons from FADH2. Electrons are sent from complex II to ubiquinone Q, which carries these electrons to complex III.
3) Complex III receives electrons from ubiquinone Q and pomps protons to the intermembrane space. Electrons are transferred to Cytochrome c.
Electrons travel from cytochrome c to complex IV.
4) Complex IV is the last complex that pomps protons to the intermembrane space.
5) Electrons are sent to O₂ molecules, which also receive protons in the matrix to create water molecules. Four electrons are needed to produce two water molecules from one O₂ molecule.
The proton gradient is used to produce ATP molecules.
In conclusion, the set of proteins in the cristae of the mitochondrion, which collectively extract the energy from reduced coenzymes to form atp, are called the electron transporter chain.

Answer:
Explanation:
1. This experiment was to find how mass and speed affect KE. This is important because if you were in a situation where you needed something to go higher, you would know to add more or less mass/speed.
To test mass, we filled the bean bag with a certain amount of water, then dropped it. After, you recorded how high it made the bean bag go. The same speed, but the same amount in the bottle, just dropped from different heights.
My hypothesis is when you have more mass, the KE will be greater. This is also the same with speed, if it is dropped from a higher place, the bean bag will launch farther than the last time.
2. Data I collected from the lab was like my hypothesis explained. When the height of the bottle increased, it made the bean bag go higher than the last. And I tested 4 different masses, 0.125 kg, 0.250kg, 0.375kg and 0.500kg. Each time the bean bag went higher on a larger mass.
A lot of times on the speed test, the bean bag would go higher than the bottle drop point, but not every time. Also, when it was dropped from the same height each time, some results varied quite a bit, like when it was dropped from 1.28 the results were 1.14 then 1.30 1.30. Mass on the other hand was all in the same number range, only once the numbers were a bit off from each other.
3. Some formulas I used were KE= ½ mv^2 and Ht v^2/2g. The first was to calculate the kinetic energy of an object, m=mass v=speed. The second was for finding out what height I needed to drop something to reach a certain speed, Ht=Height and g= Gravitational Acceleration of 9.8 m/s^2.
I used these to figure out tables that showed relationships between different things like mass and KE or speed and height. The whole time I was doing the lab, my data was going up, when there was more mass/speed there were higher values in the table.
This means that my hypothesis at the beginning was correct, more of m/s means KE will increase proportionally because they are all linear. I found it surprising when the bean bag height went over the water bottle drop mark.
4. To conclude, my hypothesis matched my data. The data values went up when more mass or speed was added. This means if I were in a situation where I needed more kinetic energy for something, I would know to increase mass or the speed of the object giving it energy.
The reason that this hypothesis is correct is when you have more mass, you have more energy. So, when you drop let's say a baseball, it isn’t that heavy so it would only launch the bean bag so far. But a bowling ball is very heavy and has lots of energy when falling because of that, it would make the bean bag go very high.
To make this experiment better, I would use a smoother material for the lever so energy wouldn’t be lost by friction from wood rubbing together. Also, maybe a scanner or video camera to more accurately record how far the bean bag went. All of these would help the lab get more precise results, maybe they could be used in a future lab.

The red tailed hawk spots a chipmunk and swoops down. What is the hawk's kinetic energy when it's going 42 m/s? The hawk still has a mass of 1 kg.
Answer:
882 Joules
Explanation:
Kinetic Energy (J) = 1/2 * m * v²
where m is the mass(kg) and v(m/s) is the velocity
Here the mass is 1 kg and velocity is 42 m/s
→ Using the formula:
→ 1/2 * 1 * 42²
→ 882 J
