Reduction

Reduction is the second step of the Calvin cycle which would be affected first by a lack of NADPH.

The Calvin cycle is the group of chemical processes that occur within the chloroplasts during photosynthesis . The three main steps in Calvin cycle are carbon fixation (Carboxylation), reduction, and regeneration of the starting molecule. In the reduction step, NADPH acts as a reducing agent which functions by transferring electrons that allow carbohydrates to be synthesized from carbon dioxide. During these step, there is transfer of two electrons and one proton to the phosphorylated compound by NADPH which produces one phosphate group to form the triose phosphates.

WILL MARK BRIALIEST How do the planets Venus and Neptune differ in terms of atmospheric composition?

azamat

The atmosphere of Venus is mostly carbon dioxide, 96.5% by volume. Most of the remaining 3.5% is nitrogen. Early evidence pointed to the sulfuric acid content in theatmosphere, but we now know that that is a rather minor constituent of theatmosphere.

The atmosphere of Neptune consists mainly of hydrogen and helium, but about 2.5-3% of the atmosphere is methane. Like Uranus, clouds in Neptune's atmosphere are composed of crystals of methane.

A person's blood type is determined by the:_______

matrenka [14]

Answer:

) Presence of specific glycoproteins on the cell membrane

Explanation:

When specif glycoproteins(antigens) or antibody are present on a cell membrane of Red blood cell,they can be used to identify the blood type.Antigens are substances capable of triggering an immune response in a cells.

In addition,they function in transport of molecules across the RBC. They help in the maintenance of the RBC,and aiding the arrest of cells capable of causing diseases to the body.

Therefore,they are good determinants of blood types,based on this two types of antigens present in a blood type.

These two antigens used for classification of blood types are the 1-the ABO antigens 2,the Rhesus antigens.

Essentially,when a WBC produces an antibody ,which is a molecule that defends the body,If this is not compatible,the antibody will recognize it as a foreign body and attack it.Thus such blood types are not compatible. Thus the antibody-antigen reaction are good for knowing and classify blood types.

Antigen can also be glycoprotein,carbohydrate or glycolipids.

Generally blood types are inherited from both parents.Therefore the antigen present on the RBC are combination of the alleles from each parent.

Are the 3 bases on the tRNA called codons or anticodons?

jeyben [28]

An anticodon is a unit made up of three nucleotides that correspond to the three bases of the codon on the mRNA. Each tRNA contains a distinct anticodon triplet sequence that can base-pair to one or more codons for an amino acid.
