In mitochondrial electron transport, what is the direct role of.

Biology
1 answer:
horrorfan [7]2 years ago
8 0

Answer:

O2 participates in cellular respiration

Explanation:

The only place that O2 participates in cellular respiration is at the end of the electron transport chain, as the final electron acceptor. Oxygen's high affinity for electrons ensures its success in this role.

Which three of the following best describe what would happen if mitosis did not take place?
vaieri [72.5K]

Mitosis refers to the procedure of cell division, in which a cell goes through a carefully mediated nuclear division, which results in the production of two genetically similar daughter cells. The mitosis comprises five active stages, that is, prophase, premetaphase, metaphase, anaphase, and telophase.  

In a single-celled species like an amoeba, it is the process of mitosis by which the cells reproduce. After undergoing through the five stages of mitosis, it is via the procedure called cytokinesis, the single cell dissociates into two similar cells, thus, completing the reproduction.  

During injury, the process of mitosis takes place to substitute the damaged cells. This repair is mainly essential for the blood vessels and skin that safeguards the organs and muscles in the body. Mitosis also assists to substitute the lost blood via a wound.  

Thus, if the process of mitosis would not take place, then the organism would remain a single-cell, asexual reproduction would not take place, and the tissues of the body would not be able to repair themselves.

which statement is false about base stacking when nucleic acids are in a double-stranded conformation?
Lilit [14]

The statement that is false about base stacking is; B. Stacking interactions are hydrophilic in nature.

<h3>What is the truth about Base Stacking?</h3>

Base stacking is defined as a common arrangement of nucleobases that are found in the three dimensional structure of nucleic acids. Bases (or base pairs) are planar, and these planes stack at contact distance , excluding water and maximizing Van der Waals interactions.

Looking at the given options, the only one that can be said to be false about the defined base stacking above as regards nucleic acids is option B.

The missing options are;

A. Stacking interactions occur when two or more bases are positioned with their rings parallel to each other.

B. Stacking interactions are hydrophilic in nature.

C. Stacking involves a combination of van der Waals and dipole-dipole interactions between bases.

D. Base stacking helps to minimize contact of the bases with water.

E. Base stacking interactions are important in stabilizing the three-dimensional structure of nucleic acids.

Explain where photosynthesis takes place? What is the function of this organelle?
Damm [24]

Answer:

Chloroplast

its function is to create chemical energy using light energy

Explanation:

Photosynthesis occurs in chloroplasts which can be compared to mitochondria because they both produce energy for the organism. The Chloroplast contains within it a pigment, chlorophyll which captures the sun's energy and turns into energy which is used to create other parts of photosynthesis. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis. Chloroplasts are one of the many organelles found in the body, and are generally considered to have originated as endosymbiotic cyanobacteria. In this aspect, they are similar to mitochondria but are found only in plants and protist.
