Answer:

Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.

<h2>Plant cell:-</h2>

plant cell have a well defined nucleus.
plant cell have plastid.
plant cell has a thick covering of wall.
plant cells have many other organelles.

<h2>Prokaryotic cell:-</h2>

prokaryotic cell has no nucleus.
it do not have plastid.
prokaryotic cell don't have any thick covering of wall or membrane.
it has no organelles body.

The set of proteins in the cristae of the mitochondrion, which collectively extract the energy from reduced coenzymes to form at

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>.

nerve networks that include both sympathetic and parasympathetic fibers that reach the same structure are called nerve networks

Lelechka [254]

Central plexuses are the name for nerve networks with sympathetic and parasympathetic fibers that all travel to the same structur automobile plexuses.

<h3>What is the term for a sympathetic and parasympathetic network?</h3>

Involuntary physiological activities including heart rate, blood pressure, breathing, digestion, and sexual arousal are regulated by the autonomic nervous system, a part of the peripheral nervous system. Sympathetic, parasympathetic, and enteric are its three physically separate divisions.

<h3>Can a nerve have both parasympathetic and sympathetic functions?</h3>

Both sympathetic and parasympathetic nerves innervate several target areas (eg the heart, the iris muscle, some salivary glands, the gastrointestinal tract and pelvic organs).

What are the three main parts of the cell cycle

andrey2020 [161]

Answer:

interphase. period of the cell cycle between cell divisions.

Mitosis. cell division in which the nucleus divides into nuclei containing the same number of chromosomes.

cytokinesis. division of the cytoplasm during cell division.

Explanation:

The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to duplication of its DNA (DNA replication) and division of cytoplasm and organelles to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells.[1] In cells with a nucleus, as in eukaryotes, the cell cycle is also divided into two main stages: interphase and the mitotic (M) phase (including mitosis and cytokinesis). During interphase, the cell grows, accumulating nutrients needed for mitosis, and undergoes DNA replication preparing it for cell division. During the mitotic phase, the replicated chromosomes and cytoplasm separate into two new daughter cells. To ensure the proper division of the cell, there are control mechanisms known as cell cycle checkpoints.
