What are some similarities and between Gigantopithecus and humans?
Basile [38]

Answer:

Gigantopithecus could stand on its hind legs, and the known jaws of Gigantopithecus widen towards the rear and proposed that this widening occurred to allow for the housing of a trachea‭ (‬the‭ ‘‬windpipe‭’ ‬that connects the lungs to the mouth opening‭) ‬when the skull was placed directly in top of the head like a human and not carried forward like a great ape.‭

Hypothesize why parts of a plant, such as the leaves, are green, but other parts, such as the roots, are not. use scientific rea
Leto [7]
No idea about the scientific reasoning, but the leaves of the plant are where the most photosynthesizing has to happen. In order for the plant to get energy it has to absorb the most light. So it creates broad leaves. The reason they are green is because chloroplasts are green. I believe that the cells in the leaves have more chloroplasts so that they can catch more sunlight.<span />

lesantik [10]

Cell respiration involves different steps, among which there is the oxidative phosphorilation that produces and stores ATP. The answer is the <u><em>electron transporter chain</em></u>.

<h3>ELECTRON TRANSPORTER CHAIN -oxidative phosphorylation-</h3>

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.

<h3>Steps in the electectron transporter chain</h3>

1) 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, <em>the set of proteins in the cristae of the mitochondrion, which collectively extract the energy from reduced coenzymes to form atp, are called the</em> <u><em>electron transporter chain</em></u>.
