Why do food chains end?

Biology
2 answers:
wolverine [178]3 years ago

All food chains start with energy from the sun. This energy is captured by plants. Thus the living part of a food chain always starts with plant life and ends with an animal. ... Animals cannot make their own food so they must eat plants and/or other animals.

DCCD (dicyclohexylcarbodiimide) inhibits oxidative phosphorylation when the substrate is mitochondrial NADH. DCCD is a drug that
VARVARA [1.3K]

Answer:

A) Decreases cellular energy production

B) DCCD also affects K+ transport

Explanation:

A) Consequences are of DCCD on cellular energy production: <em>Decreases cellular energy production</em>

ATP-synthase pump is composed of two subunits: F1 catalytic subunit that synthesizes ATP, and F0 proton pumping subunits, that transport H+ through the membrane. F1 subunit might act independently of F0 to produce ATP, but this molecule can not be released without H+ gradient, which generates a movement necessary for ATP release from the catalytic center.

When any of the parts composing F0 react with DCCD, the subunit can not transport H+ through the membrane. DCCD inhibits the enzyme activity by blocking the protons´ flow.

As DCCD blocks the protons´ flow, and the protons´ flow is necessary to release the ATP molecule from the F1 subunit, no other ADP + Pi can enter to F1 subunit, and the production of ATP stops.

B) Other cellular effects of DCCD

There seem to be other effects of DCCD on cell activity, some of which are still under study. To name a few:

  • Diimide from DCCD seems to stimulate cytochrome b reduction and inhibits its reoxidation by ferricyanide.
  • When exposing the cell to high concentrations of DCCD for a long time, might occur an alteration in the electron transporting chain
  • Inhibition of ubiquinol-cytochrome c reductase activity when exposing the cell to high concentrations of DCCD.
  • Inhibition of K+ transport, associated with the inhibition of H+ transport.

Concerning the effect of DCCD on the K+ transport, DCCD stops the extrusion of H+ and the consequent intrusion of K+.

DCCD strongly inhibits the simultaneous flow of H+ and K+. First, it inhibits H+ flow, acidification of the environment stops, but at this point, K+ keeps moving through the membrane. Once the H+ flow has ceased, the K+ flow slowly decreases until it finally stops moving. There is a lag time in the DCCD effect on K+ flow to the instantaneous effect on H+ flow.

There are three different types of rocks: igneous, metamorphic, and sedimentary. Which type of rock would you expect to find alo
slamgirl [31]

Answer: Igneous

Explanation:

The main type of rock found at divergent plate boundaries is igneous. These rocks are formed when magma cools and becomes solid, either above or below ground. They are rich in elements including silicon, aluminium, sodium, potassium, calcium and iron, and make up about 95 percent of the upper part of the Earth's crust. More than 700 types of igneous rock have been identified.

Most rocks formed at divergent boundaries are categorized as malefic igneous rocks, which are dark-coloured due to their high magnesium and iron content. This category includes basalt, gabbro and peridotites, which are often found at these boundaries.

How is heterotroph omnivore and carnivore related
BaLLatris [955]
Omnivores and carnivores are related because omnivores also eat meat and carnivores eat strictly meat. For example, a t-rex is a carnivore and a omnivore is those rhino looking dinosaurs.
