Biology
1 answer:
Yanka [14]3 years ago
7 0

Answer:

C. Coupled reactions establish an electrochemical gradient across a membrane.

Explanation:

  • During cellular respiration in mitochondria, and during photosynthesis in chloroplasts, the electron transport chain requires a proton gradient to pump protons across the membrane by active transport.
  • Protons flow back across the membrane by facilitated diffusion through ATP synthase, which utilizes them to phosphorylate ADP to ATP.
  • This process of ATP synthesis by harnessing the elctrochemicaal gradient geenrated by the diffusion of protons across the biological membrane through ATP synthase is called chemiosmosis.

Which of the following best characterizes an ecological footprint?
kotykmax [81]

Answer:

Option B

Explanation:

An economics footprint can be described as a measure of biological productivity.

Ecological footprints show a comparison of the rapidness of our resources consumption and waste generation to the rapidness of natural absorbing these wastes and also including our carbon emission.

Thus, one of the characteristics of ecological footprints is a measure of our biological productivity.

The expression of a gene to form a polypeptide occurs in two major steps. What are these two steps in their correct chronologica
Katen [24]

two steps of expression of a gene in their correct chronological order are Transcription then translation.(option a)

The process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce protein or non-coding RNA end products and ultimately affect a phenotype as the final effect is known as gene expression.

It comprises two significant stages: translation and transcription, Gene expression is made up of transcription and translation working together to form a polypeptide.

  • The production of RNA from DNA is known as transcription. The enzyme RNA polymerase acts as the catalytic agent.
  • The process by which a messenger RNA's genetic code is decoded to produce a particular polypeptide chain is known as translation. A particular amino acid is specified in each genetic code.

If one strand of a DNA molecule has the sequence of bases 5′-ATTGCA-3′, the mRNA synthesized following the template will be ____
rjkz [21]

If one strand of a DNA molecule has the sequence of bases 5-ATTGCA-3, the mRNA synthesized following the template will be 3-UAACGU-5.

Nucleotides are added to the growing strand one at a time in the precise sequence dictated by the existing  template strand. adenine and thymine are always paired with each other in the Watson-Crick DNA model, and cytosine is always paired with guanine.

The nucleotide sequence of DNA serves as a template for the nucleus, where mRNA is synthesised. The RNA polymerase II enzyme is responsible for this reaction's catalysis and needs nucleotide triphosphates as its substrates. Transcription is what happens in the nucleus when DNA is converted into mRNA. The cytoplasmic synthesis of proteins is controlled by the mRNA. The cytoplasm is where the mRNA that is produced in the nucleus attaches to the ribosomes after being transported from the nucleus. The nucleotide sequence of the mRNA serves as a guide for the assembly of proteins on ribosomes. The cytoplasm receives a "message" from the nucleus via mRNA. The nucleotide sequence of the mRNA, which is complementary to the nucleotide sequence of the messenger RNA, encodes the message.
