At the end of glycolysis whats is transported to the mitochondria to serve as a starting point for the Krebs cycle?

Pyruvate is transported to the mitochondria to serve as a starting point for the Krebs cycle. Once in the mitochondria, pyruvate is converted into acetyl-CoA, which then enters the Krebs cycle to be oxidized for energy production.


What is another name for nutrient cycles in ecosystems?

The dead organic matter are an example of nutrient cycle and can sometimes be buried under sediment, rendering the carbon unavailable to living organisms.


Modern farming practices speed up the decomposition of matter in soil how might this affect the nitrogen cycle?

Modern farming practices can disrupt the nitrogen cycle in soil by accelerating the decomposition of organic matter, leading to increased nitrogen loss through leaching and runoff. This can result in decreased soil fertility and the need for synthetic nitrogen fertilizers to maintain crop productivity.


What is the cycle involving the exchange of nitrogen between organisms and the atmosphere?

The nitrogen cycle involves the process of nitrogen fixation by certain bacteria converting atmospheric nitrogen into forms usable by plants, which are then consumed by animals. Decomposers break down organic matter into ammonia and return nitrogen to the soil. Denitrification by bacteria converts nitrates back to atmospheric nitrogen to complete the cycle.


What role does bacteria play in the nitrogen cycle?

Bacteria play a crucial role in the nitrogen cycle by converting nitrogen gas in the atmosphere into forms that plants can use, a process called nitrogen fixation. Other bacteria help break down organic matter and release nitrogen back into the soil, completing the cycle.
