It is a true statement.

ATP synthase is the primary functioning of enzymes. A proton pumping transmembrane is powered by ATP hydrolysis which is very important. For example; ATP produces anaerobic bacteria by fermentation then ATP synthase uses ATP which helps to generate proton motive force which is necessary for flagella motility and ion transport.

ATP synthase is in both ways where bacteria can live from photosynthesis or respiration and also in fermentation. In order to avoid wasting ATP hydrolysis, it is significant to control ATP-driven proton by pumping activity.

Describe the key features of the Watson-Crick model for DNA structure.
vagabundo [1.1K]

Answer:

Watson and Crick proposed the double helical model of DNA.

Explanation:

- This model says that DNA exist as double helix. It has two polynucelotide strands running in opposite direction i.e the strands are anti-parallel.

- Each polynucleotide strand is made up of several nucleotide liknked together by phophodiester bonds.

- The two strands are not coiled upon each other but the double strand is coiled upon itself around a common axis like the spiral stair case. Here base pairs forms the stairs and backbone of two strands form railing. Back bone contains sugar and phosphate.

- The base pairing is specific, adenine always pairs with thymine and guanine always pairs with cytosine. Thus if we see any base pair, it consists of one purine and one pyrimidine.

- The two strands of DNA thus show complementary base pairing.

- The strands are held together because of hydrogen bonding between the bases in opposite strand.

- One full helical turn involves ten base pairs and the base pairs are stacked  3.4 A apart.

- This form is called as B-form of DNA.

Which of the following statements about the smooth endoplasmic reticulum is/are correct?
Vlada [557]

Answer:

  • Liver cells are abundant in SER.  
  • The testes and ovaries are tissue types whose cells are abundant in SER.
  • Cholesterol is made in the SER.
  •  Phospholipids are synthesized from cytosolic water soluble precursor molecules.  

Explanation:

This is because liver cells contain enzymes that metabolize various lipid-soluble compounds.

This is because testes and ovaries produce steroid hormones (cholesterol is the precursor for their synthesis).

ER is the organelle at which all membrane lipids are synthesized.

Phospholipids are the main lipids that are the main structural components of the cell membrane. They are synthesized on the cytosolic side of the ER membrane, from water-soluble cytosolic precursors.

Mitosis and meiosis similarities
Artist 52 [7]

The alternation of generations in the life cycle of a plant includes the diploid and haploid multicellular stages. diploid and haploid are copies of the chromosomes. The spores in the plant is unicellular and when they start dividing through mitosis, it produces identical cells. These identical cells are all haploid. Haploid stages contain one set of chromosome from either of the parent. These identical cells create a multicellular system called the gametophytes. A gametophyte is the haploid multicellular stage in the life cycle of a plant. The gametophyte makes the gametes. These gametes are responsible for sexual fertilization. It takes place when a sperm (male gametes) from the male fuses into the egg cell (female gametes) of the female. The formation of both male and female gametes creates a diploid zygote. Diploid stages contain one set of chromosome from each parent. This is where the sporophyte comes in. A sporophyte is the diploid multicellular stage in the life cycle of the plant. It now contains the two sets of chromosomes from each parent.

The type of cell division that produces gametes with half the normal chromosome number is the meiosis. Meiosis is the type of cell division used in sexual reproduction. It will occur in the testes and ovaries.
