The energy release from sequential redox reactions provides energy to cells most directly by Using that energy to pump protons.
- By transferring electrons during chemical reactions, catabolic pathways break down organic molecules, generating energy that is then used to produce ATP.
- In an oxidation-reduction (redox) reaction, the process of losing electrons (making a chemical more positive) is referred to as oxidation, while the process of gaining electrons (making a substance more negative) is referred to as reduction.
- The inner mitochondrial membrane's electron transport chain receives electrons from NADH and FADH2, which causes an H+ accumulation in the inner membrane space.
- The direct energy source for ATP synthesis is this proton gradient (gradient of H+) flowing via the membrane enzyme complex ATP synthetase.

Answer:
RNA
Explanation:
Transcription is the first process of protein synthesis and it involves copying the information encoded in the genetic material (DNA) to a RNA molecule. It involves making a complementary strand of mRNA from a DNA template.
The process of transcription commences when an enzyme called RNA polymerase binds to the promoter region of a gene on the DNA, signalling the unwinding of its double-stranded structure. The RNA polymerase then adds nucleotides to the growing RNA molecule, complementary to the ones it reads on the DNA. The RNA synthesized during transcription is called messenger RNA (mRNA).
The mRNA is then used as a template for amino acids synthesis during translation.
Answer:
Blood is composed of several types of cells:
- <u>RED BLOOD CELLS</u>: They are the oxygen carriers of the body i.e. they pick up the oxygen as the blood goes through the lungs & release of oxygen to cells.Also known as erthrocytes
- <u>WHITE BLOOD CELLS</u>: also known as leukocytes.They are the soldiers of the body.Aims at fighting against the infections ( caused by bacteria & virus)
- <u>PLATELETS</u> : helps in the blood clot in response to any wound or injury
There are five types of white blood cells & approx %age they made up in blood are:
•Neutrophils (55% to 70%)
•Band neutrophils (0% to 3%)
•Lymphocytes (20% to 40%)
•Monocytes (2% to 8%)
•Eosinophils (1% to 4%)
•Basophils (0.5% to 1%)
When children are more than 4 year old they have higher % age of lymphocytes than the adults do.
Answer:
The Galactic Center (or Galactic Centre) is the rotational center of the Milky Way galaxy; it is a supermassive black hole of 4.100 ± 0.034 million solar masses, which powers the compact radio source Sagittarius A*.
It is any property that is measurable, whose value describes a state of a physical system
Hope this helped :)
