In its role as an antioxidant, _____ guards cell membranes, body proteins, dna, and cholesterol, and thus helps prevent heart di

vodka [1.7K]

Answer:

The answer is Vitamin E or α-tocopherol.

Explanation:

Vitamin E is a fat-soluble vitamin is first absorbed in the small intestine and is then stored at the liver. It is an antioxidant which protects cells from free radicals or reactive oxygen species (ROS). It can also prevent bad cholesterol from depositing in the blood vessels.

Vitamin E can be naturally found in nuts, seeds, and vegetable oils. As a dietary supplement, it takes the form of α-tocopherol. The RDA depends on the age of the person, as it may range from 4 mg to 15 mg per day.

Vitamin E deficiency is so rare that it will only occur if the person has a fat malabsorption illness like Crohn's disease, abetalipoproteinemia, etc. Symptoms of deficiency include muscle weakness, retinal degradation, peripheral neuropathy, and an immunocompromised state.

loris [4]

Answer:

10. View the slides on the PowerPoint to match each of the cell structures with the correct letter labels for

each of the following cells.

Elodea Cell Cell wall _B____ Chloroplast _A___ Area of vacuole _C__ Onion Cell Cell wall _B__ Nucleus __A_ Mitochondria _C__ Cheek Epithelial Cell Cell membrane _B__ Nucleus __A_ BacteriA Bacterial Cells. View the bacterial cells on the PowerPoint and identify which cell (A, B, or C) is: Coccus ________B____ Bacillus ______A______ Spirillum ______C______ Protista Amoeba can move via the extension of finger-like projections called pseudopodia

Explanation:

Amoeba can move via the extension of finger-like projections called pseudopodia, what prevents plant cells from moving in the same fashion?

Ans: The plants that prevent the information of pseudopodia have rigid cell walls. which is unlike to amoeba.

How does the euglena compare to both plant and animal cells (i.e. - explain what structure(s) might make it similar to plants and what structures might make it similar to animals).

Ans: Euglena are similar to plants because they both have chloroplast and are similar to animals because neither has a cell wall.

The classical point of view is that, during mitochondrial respiration, three ATP molecules can be generated from one molecule of

Stells [14]

Answer:

38

Explanation:

In eukaryotic cells, the maximum production of ATP molecules generated per glucose molecule during cellular respiration is 38, i.e., 2 ATP molecules from glycolysis, 2 ATP molecules from the Krebs cycle, and 34 ATP molecules from the Electron Transport Chain (ETC). In vivo (i.e., in the cell), this number is not reached because there is an energy cost associated with the movement of pyruvate (CH3COCOO−) and adenosine diphosphate (ADP) into the mitochondrial matrix, thereby the predicted yield is approximately 30 ATP molecules per glucose molecule. In aerobic bacteria, aerobic respiration of glucose occurs in the cytoplasm (since bacteria do not contain membrane-bound organelles such as mitochondria), and thereby, in this case, it is expected that aerobic respiration using glucose yields 38 ATP per glucose molecule.
