Why is rubisco so prevalent and important?

Biology
1 answer:
BartSMP [9]2 years ago
5 0

Answer: RuBisCO is very important in biology and ecology because it catalyzes the primary chemical reaction by which inorganic carbon permanently enters the biosphere. RuBisCO is also the most abundant protein in leaves and the most abundant protein on Earth.

if the job of a cell was to swim a long distance to an egg with a flagella, then it would need more of what organelle?
kicyunya [14]
If a particular job of a cell was to swim a long distance to an egg with a flagella, then it would need more mitochondria. As mitochondria undergo cellular respiration and essentially utilize the carbohydrates for that particular cell to produce the final product of ATP high energy containing molecules needed for the movement.

A population of white-tailed deer inhabits a certain patch of forest in michigan. Which group of alleles can be considered the g
emmainna [20.7K]

Answer:

the dominant alleles of white-tailed deer in this population only!

Explanation:A group of individuals of the same species that interbreed with each other is known as a population. The study of change in genetics is called population genetics which includes genes and alleles.  

Complete set of genes and their alleles that are present in a population is called gene pool. Gene pool includes both dominant and recessive alleles of every gene present in a population that can be transmitted in the next generation.

Population with high genetic pool has high diversity which increases the fitness of a population. As gene pool include all the genes and its allele in a population, therefore, the correct answer is all alleles of the white-tailed deer in this population only.

What is the determining factor for the transcription of structural genes of the trp operon?
padilas [110]

The right answer is 3. the availability of tryptophan in the environment

The TRP operon regulation depends on the availability of the tryptophan molecule (it depends if the cell need tryptophan or already has it).

There are two modes of regulation of the trp operon: Suppression and Mitigation

*Repression

The synthesis of operon mRNA is controlled by a repressor that blocks transcription when bound by tryptophan, which acts as a co-repressor.

The repressor, a 108 aa homodimer (ie 2 apo-repressor), has helix-turn-helix domains that interact with inverted repeats at the major groove of the operator, thus allowing its fixation.

In the absence of trp, the repressor is inactive and does not attach to the operator. The RNA polymerase can bind to the promoter and transcribe the trp E, D, C, B, A structural genes.

In the presence of trp, the repressor changes conformation and becomes active, so it binds to the operator, preventing RNA polymerase from accessing the promoter so transcription will not occur.

* The Attenuation

This is a premature termination of transcription that is a function of Trp concentration. It takes place at a late moment of transcription while regulation by repression is done during the initiation.

1st Case: Low Trp Rate, Continuous Transcription, → Formation of the Anti-attenuator in the absence of trp, and therefore the synthesis of tryptophan is continued.

2nd case: High rate of trp, stop transcription, → Formation of the attenuator in the presence of trp. This one will attenuate the synthesis of tryptophan.
