Electron carrier molecules transfer electrons between metabolic pathways. Choose the electron carriers that transfer electrons f

rom glycolysis to the electron transport chain and from the citric acid cycle to the electron transport chain. One of the molecules will be placed more than once. More than one molecule may act as an electron carrier in these two pathways.

Answer:

from glycolysis to electron transport.-glycolytic pathway

NADH  and FADH2 are the major electron carrier   from glycolysis through the Kreb Cycle to the electron transport chain.

Note-NADH  alone transports electron  from glycolysis  to the Kreb Cycle. while both   NADH and FADH2  transport electrons   from the kreb'cycle  to the electron transport chain.

from citric ac id cycle to the electron transport chain.

as explained above both NADH and FADH2.

The electrons are  in the hydrogen atoms, carried by these co-enzymes. When they reached the matrix, the hydrogen atoms are split into protons and electrons(p and e-). it is these electrons that form gradients which are transported as chains in the matrix. The gradients of the electron generated PMF for pumping Hydrogen atoms into the intramembrane of mitochondrial

Note.

Nicotinamide Adenine Di nucleotide Hydrogen(NADH)

Flavin Adenine Dinucleotide Hydrogen(FADH)

The nutrition label for a food product shows the total amount of fats in grams. One gram of fat provides nine calories of energy
Gala2k [10]

Directly on the label, it says there are 110 calories from fat per serving. However, it also says that there are 12 grams of fat, and 12 x 9 = 108. Depending on what your teacher is looking for, the answer could be 108 or 110.

<h3>What is fat in food?</h3>

A small portion of fat is an important part of a healthy, balanced diet. Fat is the basis of important fatty acids, which the body cannot make itself. Fat helps the body absorb vitamin A, vitamin D and vitamin E. These vitamins are fat-soluble, which suggests they can only be interested with the help of fats.

Thus, this could be the answer.

The sun's energy is absorbed by plants and converted into glucose during __________. Animals eat the plants and convert the gluc
blagie [28]
<span>B) photosynthesis; cellular respiration 

Photosynthesis is the process of how plants make their food. They use sun's light, water and CO2 to make glucose and turn it into energy. 

</span>Cellular respiration involves a series of chemical reactions.<span>The reactions that are catalysed by enzymes actually helps the organism to grow, respond to various changes in the environment, reproduce and continue maintaining their own structures. Cellular respiration is also considered a part of the metabolism process. This process actually helps in carrying the oxygen through the blood. </span>

Eric has made a terrarium, a closed container with plants in it, and he has put
Alexxandr [17]

Answer:

Yes

Explanation:

The water will be used by the plants sooner or later so their basic metabolic needs can be achieved. Also, the plants will loose their water by transpiration, in order to produce their carbohydrates. Therefore the amount of water will not be enough and has to be replenished.

The various parts of the endomembrane system serve different functions in the cell. In this activity, you will identify the role
mixas84 [53]

Answer:

1. protein synthesis - (b) rough ER

2. protein modification and sorting - (c) Golgi apparatus

3. macromolecule digestion - (d) lysosomes

4. lipid synthesis - (a) smooth ER

5. autophagy - (d) lysosomes

6. cisternal maturation - (c) Golgi apparatus

7. calcium ion storage - (a) smooth ER

8. poison detoxification - (a) smooth ER

Explanation:

Rough ER or rough endoplasmic reticulum with the help of ribosomes is responsible for protein synthesis and their subsequent transport to various other parts of the cell that is why both these organelles are also known as protein factory.

Soon after proteins are synthesized with the help of rough ER, they are transported to another network of organelle known as golgi apparatus. In golgi apparatus, the nascent protein is further modified and sorted. Modification and sorting of proteins help in identifying their final destination i.e. whether the protein is meant for mitochondria or plasma membrane or some other organelle. Maturation of cisternae also takes place in golgi apparatus.

Smooth ER or smooth endoplasmic reticulum is responsible for lipid synthesis, storage of calcium ions and poison detoxification. Most of the steroid hormones, triglycerols etc. are synthesized in the smooth endoplasmic reticulum. Smooth ER also stores calcium ions so that whenever they are required they can be sequestered back into the cytosol. Poison detoxification occurs in the smooth ER of liver because the enzymes present in the liver are capable of converting such hydrophobic substances into hydrophilic substances so that they could be easily secreted out of the body.

Lysosome is the organelle which is responsible for macromolecule digestion and autophagy. Lysosomes have very low pH and a lot of hydrolyzing enzymes which can easily digest macromolecules. Autophagy is a self degradable process in which damaged cells are eaten or destroyed by lysosomes so that their macromolecules could be broken down into their monomers so that they can be reused by our body.

Helga [31]

Answer:

<em>Jansky Very Large Array </em>

Explanation:

It Is most powerful telescope on Earth and  is located on the plains of San Agustin near Socorro, New Mexico, US. This telescope consist of 25 antennas whose collective ares is equal to a single 430 foot antenna. The angular resolution is equal to an antenna of 22 miles in diameter.  It is also possible to adjust its arms to change its resolutions. There is receiver in each antenna that can operate from wavelength range of 4 mm to 7 metres. National Radio Astronomy Observatory is in charge of this telescope.
