3. How do multiple transmembrane proteins get inserted correctly into the membrane?

Biology

Multiple transmembrane proteins get inserted correctly into the membrane thanks to signaling sequences.

The amino acid chain of transmembrane proteins (pass through a membrane one or more times) are inserted into the membrane by translocation. Transmembrane proteins must enter the ER before their insertion in cytoplasm and their transport is co-translational (the process of translocation occurs while the protein is still being synthesized on the ribosome). Protein should contain:  

• Signal peptide or signal sequence is a sequence of amino acids at the N terminal that gets recognized by signal recognition particle (SRP). This sequence is involved in cotranslational translocation into ER, where the protein should be folded.

• A stop-transfer sequence-signals that translation of the protein should continue in the cytosol (not in ER).

Volgvan

Answer:

Only one of the three statement is true; and that is,

(ii.) Different metabolic end products result from the two types of fermentation

Explanation:

Fermentation is the process by which organic molecules such as glucose are broken down into smaller molecules to extract energy as ATP in the absence of oxygen.

Fermentation is carried out by many organisms including man.

In man, fermentation occurs in very active skeletal muscles such as in an athlete running. It involves the reduction of pyruvate produced from the glycolytic pathway to lactate in the muscles. The net yield of ATP from glucose breakdown to produce lactate is 2 ATP molecules.

In microorganisms such as yeast, the fermentation product of py ruvate derived from glycolysis is ethanol and carbon dioxide, CO₂. The net ATP yield in fermentation of glucose in yeast cells is also 2 ATP molecules.

From the options provided in the questions, the correct option is:

Only one of the three statement is true and that is that, ii. Different metabolic end products result from the two types of fermentation.

Explain how the taiga is different from the other forest ecosystems.
serg [7]

Taiga is a winter type forest. Taiga is different then other ecosystems because other ecosystems are not has cold has Taiga. Taiga ecosystems can get has low has -70 °F (or -60° C)

But Taiga ecosystems can get has hot has 104°F (or 40°C)

Taiga ecosystems can get colder then tundra (which is another very cold too)

Some things that make the Taiga ecosystems unique is:

  1. Evergreen trees, the Taiga is COVERED with these.

Hope this helps!

Any extra info can be provided!

I think the answer is most likely be J.

The first (F) one the population of the predator increases hugely while the population of the prey was neutral. And so both population didn’t seem to have any connection. Same goes for H. Graph G doesn’t make sense at all the population of the prey didn’t exist throughout the time in the graph but only exist in one single point of time and then just vanish again so that shouldn’t be the answer either.
In graph J, you can see the correlation between the two populations as the predator goes up and so does the prey.
You can search up on google predator-prey relationship graph to get better understanding.
