How do large, mature plant cells compensate for inefficient import and export associated with a lower surface area-to-volume rat
io? a. Large plant cells have increased lysosomic activity to increase import and export of substances to and from the membrane.
b. Large plant cells have a large water-filled vacuole in the center, decreasing the active cytoplasm volume.
c. Large plant cells have adapted a more efficient metabolic system, whereby fewer nutrients are needed for the structures located at the center of the cytoplasm.
d. Large plant cells maintain a large storage vacuole in the center that stores nutrients for use in the interior of the cytoplasm.
Answer - D. <span>Large plant cells maintain a large storage vacuole in the center that stores nutrients for use in the interior of the cytoplasm.
Reason - Dude really. What are you guys learning in biology LOL. Any ways heres the reason why i chose this answer.
Starting off plant cells of course need storage for variety of nutrients and to store for future use when its needed for the necessary requirements for its survival or growth. Now it Compensates it by having one large vacuole in the middle that takes up roughly 75-80%. Unlike us humans having one in the cell we have it small because its temporary from here to there. But plant cells need it more because they can also store water and as such variety of nutrients. Just like I said before.</span>
In anabolic reactions that involve the synthesis of a large molecule from smaller precursor molecules, NADH and ATP are consumed when they provide the needed electrons or energy.
In catabolic reactions that involve the breakdown of a molecule into smaller subunits, such as glucose to pyruvate, NADH and ATP are produced.
In the reaction Pyruvate +NADH-Lactate +NAD, pyruvate is being reduced.
In the reaction Pyruvate NADH-Lactate +NAD, NADH is being oxidized.
Explanation:
Being involved in synthesis, anabolic reactions require energy in the form of energy storing molecules such as NADH and ATP. Anabolic processes utilize energy produced by the catabolism of complex compounds.
Catabolic processes produce energy or energy storing compounds by breaking down complex substances into simpler ones. All steps of cellular respiration are catabolic processes since they generate energy in the form of ATP or energy yielding molecules such as NADH and FADH2.
Anaerobic respiration takes place during intense physical activity due to which adequate oxygen does not reach the cells. Insufficient oxygen shuttles the pyruvate molecules produced by glycolysis into the lactic acid pathway that reduces pyruvate into lactic acid.
Since, NADH is donating its H+, it is being oxidized to NAD+.
