Why is continental crust usually older than oceanic crust?

Biology
2 answers:
ANTONII [103]3 years ago
7 0

Answer:

On balance, the age of the continental crust (of a continent) will be older than the oceanic crust because the continental crust is not being recycled (to the extent that the oceanic crust is recycled)! To understand this phenomena you have to first understand where the oceanic crust is formed and where it subducts.

Answer:

Continental crust rarely gets destroyed and recycled in the process of subduction. Oceanic crust gets colder and denser with age. It gets dense to the point that it sinks in the upper mantle. The continental crust is lighter than the oceanic crust. The continental crust doesn't subduct.

. In which phase of cellular respiration is glucose a substrate?​
vodka [1.7K]

Explanation:

During glycolysis, enzymes act on the substrate, glucose. Glycolysis occurs in the cytoplasm; here, 2 molecules of ATP are used to cleave glucose into 2 pyruvates,  4 ATP and 2 electron carrying NADH molecules.

Further Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP.  At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

  • Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates,  4 ATP and 2 electron carrying NADH molecules.
  • The Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate,  2 ATP oxygen molecules, 8 NADH and 2 FADH2.
  • The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2,  renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

Which kingdom or supergroup is characterized by organisms that are heterotrophic by ingestion?
Akimi4 [234]
The kingdom described above is the kingdom Animalia. Heterotrophic mode of nutrition is a type of nutrition in which organisms depends upon other organisms such as plants for survival, for example all animals are heterotrophic and obtain all organic materials they need to survive. The other type of nutrition is the autotrophic mode of nutrition in which organisms use simple inorganic substances to synthesize organic molecules, a characteristic of plants.
