Explain why glucose consumption must increase in hypoxic tissues to provide the same amount of ATP that could be produced from g

lucose in normoxic (normal O2 levels) tissues.A) Oxygen is the limiting reactant in ATP producing, so ATP is produced in hypoxic tissues slowlier than in normoxic tissuesB) In hypoxic tissues, in contrast to normoxic tissues, ATP is additionally consumed to transform lactate to pyruvate.C) In hypoxic tissues, ATP is produced only by glycolysis, whereas in normoxic tissues, the citric acid cycle + oxidative phosphorylation can be used.D) In hypoxic tissues, ATP is produced only by glycolysis, whereas in normoxic tissues, the citric acid cycle + oxidative phosphorylation can be used.

Answer: B. In hypoxic tissues, in contrast to normoxic tissues, ATP is additionally consumed to transform lactate to pyruvate

Explanation:

In hypoxic tissues such as new cancerous cells, the vascular system is still underdeveloped, thus oxygen supply is reduced. To meet energy need, additional glucose is needed to convert lactate (result of anaerobic glycolysis) to pyruvate which can then go into the TCA cycle to yield energy. This phenomenon is very common in muscle tissues during exercise.

Explain why ions do not move through ion channels by only simple diffusion, whereas water does move through water channels by si
cluponka [151]

Answer:

Electrical gradient.

Explanation:

Ions DO NOT move in Ion channels by simple diffusion because most ion channels can be:

I) selective of ions pass through it.

II) operating on a "open and close" principle. Where it opens or close on its own accord OR does so ONLY when induced by a specific influence like change in voltage of ion channels.

IN ADDITION to the concentration gradient, ELECTRICAL GRADIENTS (change in membrane voltage) affects the movement of ions through ion channels

An extreme disturbance happens in an ecosystem. How does an ecosystem change as succession happens after this disturbance?
ddd [48]

Answer:

There is less biodiversity in the ecosystem.

Explanation:

Since the barren ground doesn't provide suitable living conditions for most of the living organisms, the ones that need the lest resources to survive create the primary succession, usually the mosses and lichens. The organisms of the primary succession provide biomass, so the ground is mixing with it, thus new soil is forming.
