Identify the type of neuronal cell that detects bright light and provides high-resolution color vision.

Biology

Answer:

The correct option is b. cones.

Explanation:

Cones and rods are specialized cells, called photoreceptor cells, that are found in the retina and are responsible for our vision.

Cones, allow to the human eye to have a visual acuity (ability of the eye to resolve, transmit sharp images and perceive small details in an object) and provide sensitivity to the color, are more concentrated in the central yellow spot known as the macula.

There are three different types of cones in color reception: "L cones" (sensitive to long wavelength, which is red), "M cones" (sensitive to medium wavelength, which is green) and "S cones" (sensitive to short wavelength, which is blue). Since color perception depends on the activation of these three types of nerve cells, it follows that the visible color can be determined based on three numbers called triestimulus values.

The rods are necessary for the perception of light and darkness and to adapt to night vision, because they are very sensitive to low intensity light. On the contrary, they become completely blind to bright light and, therefore, lack importance with regard to daytime vision or visual acuity.

In the Calvin cycle the conversion of energy poor carbon dioxide into energy rich glucose
rodikova [14]

Answer:

D)NADPH is made

A)ATP is used

Explanation:

Sorry to ask the two questions, I asked why the two options are in the process:Reduction. In the second stage, ATP and NADPH are used to convert the 3-PGA molecules into three-carbon sugar molecules, glyceraldehyde-3-phosphate ( G3P ). At this stage, it gets its name because NADPH donates, or reduces , electrons to a three-carbon intermediate to form G3P.[Ocultar detalhes]

The reduction stage of the Calvin cycle, which needs ATP and NADPH, converts 3-PGA (produced in the fixation stage) into a three-carbon sugar. This process takes place in two main stages:

Simplified diagram of the reduction step of the Calvin cycle showing the carbon atoms, but not the complete molecular structures. A 3-PGA molecule first receives a second phosphate group from ATP (generating ADP). Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.

A 3-PGA molecule first receives a second phosphate group from ATP (generating ADP). Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.

First, each 3-PGA molecule receives a phosphate group from ATP, becoming a doubly phosphorylated molecule called 1,3-bisphosphoglyceride (and leaving an ADP as a by-product).

Second, 1,3-bisphosphoglycerate molecules are reduced (gain electrons). Each molecule receives two electrons from NADPH and loses one of its phosphate groups, becoming a three-carbon sugar called glyceraldehyde-3-phosphate (G3P) . This step produces NADP^+

The ATP and NADPH used in these steps are products of the photo-dependent reactions (first stage of photosynthesis). That is, the chemical energy of ATP and the reducing potential of NADPH, both produced with the use of light energy, keep the Calvin cycle running. Conversely, the Calvin cycle regenerates ADP and NADP^+

+

start superscript, plus, end superscript, providing the necessary substrates for photo-dependent reactions.
