Anuta_ua [19.1K]

Answer

          The three metabolic pathways that make up aerobic respiration are really all parts of one larger pathway because the products of early pathways (like NADH) become <u>utilize</u> in the last one.

Explanation

         Aerobic respiration is that type of respiration in which glucose molecule is broken down into CO2 and H2O in the presence of oxygen and 36 or 38 ATP molecules are produced.

Aerobic respiration complete in four main steps:

1. Glycolysis

                  In this step glucose is broken down into 2 molecules of pyruvate acid along with the production of 2 ATP molecules and 2NADH.

2. Oxidation of pyruvate

                In this step pyruvate are oxidized in the presence of co-enzyme A to become Acetyl Co-enzyme A.  Again 2NADH are formed in this step.

3. Kreb Cycle

            It occus in mitochondria. Here acetyle coenzyme A enter Carbon fixation, reduction and regeneration phase. In this cycle 6 NADH, 2FADH2 and 2ATP are formed.

4. Electron transport chain

            All NADH that are produced in above steps get oxidize and help in the production of ATP along with the release of electron and proton that help in the formation of water.

Which part of the microscope is used to make small adjustments in the image of an object?
Rus_ich [418]

Answer:

The part of the microscope that is used to make small adjustments in the image of an object is the fine adjustment.

Explanation:

In the optical microscope, the fine adjustment knob allows precise focusing of the sample being studied.  This means making minimal adjustments in order to better observe the microscopic image.

After the initial focusing with the coarse adjustment knob, with the fine adjustment it is possible to highlight the details that require more attention, as well as the refringency of the sample, if it exists.

The other options are not correct because:

<em>     A. </em><em><u>Eyepiece</u></em><em>  is the lens that receives the image from the objective lens, that has contact with the eyes of the observer.</em>

<em>     C. </em><em><u>Coarse Adjustment  </u></em><em>is the rough magnification, used for the initial approximation of the image.</em>

<em>     D. </em><em><u>Objective lens</u></em><em> enlarges and defines the image of the sample on the slide.</em>
