Summarize the main events of the electron transport chain

Biology
1 answer:
Masja [62]3 years ago
4 0

The electron transport chain linked with chemiosmosis constitutes the second stage of aerobic respiration. ATP is produced by the electron transport chain when NADH and FADH2 release hydrogen atoms, regenerating NAD+ and FAD.

Drosophila eye color is an X-linked trait. Red eye color is dominant, and white eye color is recessive. Which Punnett square sho
Ira Lisetskai [31]

Answer:

Second Punnett on the first attachment.

Explanation:

In a 4 x 4 Punnett there are a total of 4 squares. Twenty five percent (25%) of 4 is 1. This means that only 1 square out of the 4 should have the genotype that you are looking for.

Okay going at it in a biological sense. Because red eyes is dominant, we know that the allele should be represented by a capital R. It is X-linked, so it should be on the X. The problem is looking for the probability of a male offspring so the combination should be XY (this means the offspring is male, XX is for females).

So taking that all together, you're looking for the genotype combination:

X^{R}Y

So you need to find the Punnett that has only 1 square with this combination. The attachment shows which specific Punnett:

Bacteriorhodopsin pumps protons across the bacterial plasma membrane from the cytosolic side to the extracellular side of the me
julsineya [31]

Answer: Option B.

B. The chromaphore retinal absorbs a photon of light, causing a double bond in retinal to isomerize from trans to cis configuration.

Explanation:

Bacteriorhodopsin is a protein used by archaea or half bacteria that pumps proton across membrane by using the light energy from sun to move protons across membrane. It is found in purple membrane of archaea cells which is known as two dimensional crystalline patches.

It captures photon energy through chromophore retina which is covalently bound and transporting the photons against their electrochemical gradients from the cytoplasm to the extracellular space.

Explain how Newton's first law derived from Newton's second law.
KATRIN_1 [288]
The second law describes the relationship between force, mass and acceleration; like Force (Newtons) equals Mass Time Acceleration. Newton's first law defines inertial reference frame as that reference frame where an object will move with constant velocity if no forces are acting on point mass.

Hope this helps you =)

Which of the following is not a function of<br> Proteins
Shtirlitz [24]

Answer:  

anything contrary to the information provided below

Explanation:

Proteins determine the shape and structure of cells and the direction of almost all vital processes. Protein functions are specific to each of them and allow cells to maintain their integrity, defense of external agents, damage repair, control and regular functions, etc. selective binding to molecules. Structural proteins agree with other molecules of the same protein to cause a larger structure. However, other proteins bind to different molecules: antibodies to specific antigens, hemoglobin to oxygen, enzymes to their substrates, regulators of genetic expression to DNA, hormones to their specific receptors, etc.
