Answer:

ATP and NADPH

Explanation:

The photosynthetic process carried out by plants involves two distinct stages: the light-dependent stage and the Light-independent stage. The light-dependent stage occurs in the thylakoid membrane of the CHLOROPLAST and it involves a series of chemical reactions that results in the formation of an energy storage molecule (ATP) and reduced electron carrier (NADPH).

These molecules enters the Calvin cycle or light-independent stage. The chemical energy of ATP and reducing ability of NADPH are used to phosphorylate and reduce a 3-carbon compound (PGA) in the Calvin cycle. These two molecules (NADPH and ATP) are important to keep the Calvin cycle in place. Hence, the Calvin cycle is dependent on the light reaction and this two molecules link the two stages.

Answer:

Alternative splicing explains how it works

Explanation:

Two different transcripts can be produced from one single gene according to the nature of exons and introns of every transcript, which means that a group of exons will form the future mRNA molecule. The nature of this phenomenon is based on the function and local that every transcript will act. These mRNA transcripts are the result of how the RNA polymerase and transcription factors interacts with DNA molecule and therefore selects the number and the size of the exons and introns of each mature mRNA transcript.

How could you determine the identity of a bacterium?

cestrela7 [59]

Answer:

THE RELATIONSHIP OF IDENTIFICATION TO BACTERIAL CLASSIFICATION AND NOMENCLATURE. In order to identify an unknown bacterial isolate, the characteristics of the isolate must be compared to known taxa. In microbiology, the basic taxonomic unit is the species, and groups of related species are placed in the same genus.

What are stem cells?

Effectus [21]

Answer:

Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. There are two main types of stem cells: embryonic stem cells and adult stem cells

Explanation:

Totipotent (or Omnipotent) Stem Cells.

Pluripotent Stem Cells.

Multipotent Stem Cells.

Oligopotent Stem Cells.

Unipotent Stem Cells.
