Why is an ecosystem's net primary production (NPP) lower than its gross primary production (GPP)?

Lubov Fominskaja [6]4 years ago

Hi. I think it would be A. Heres how NPP and GPP work:

NPP stands for net primary productivity and GPP means gross primary productivity. GPP is basically the entire amount that an ecosystem or area has. NPP is the amount minus the amount lost to the environment. You might already know that as you go up the food chain energy is lost in respiration and doesn't get absorbed by the thing that eats it. Therefore, the NPP=GPP-lost energy. 

If you have any questions about this please comment :) sorry if this was unclear at all.

Complete the model of the lactic acid fermentation process.
Zina [86]
For the process of transformation of glucose into pyruvate, NAD⁺ is converted into NADH. These same NADH molecules are then reutilised on the pyruvate to lactic acid reaction and are therefore transformed back into NAD⁺ molecules that will again be used for another glycolysis reaction.
From the first rectangle, on the left, to the last rectangle, on the right, it comes NAD⁺ - NADH - NADH - NAD⁺.

vampirchik [111]

Answer:

The correct answer will be- Cargo vesicles

Explanation:

The product of the gene expression is known as the protein which is formed as the result of the transcription and translation.

The process of translation takes place in the ribosomes attached to the endoplasmic reticulum after which the proteins enter the lumen of the endoplasmic reticulum.

The protein then enters the secretory pathway which represents the movement of proteins by packaging them in cargo vesicles attached with the cargo proteins.

Thus, Cargo vesicles are the correct answer.
