What is pollination? Identify three ways pollen can be transferred. How is cross-pollination different
Stells [14]

Answer:

The transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization. It can be transferred by things that feed from what has pollen. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

If the atp synthase for an organism contains 15 c subunits, how many protons must flow through atp synthase per each new atp tha
anastassius [24]

Each time a new ATP is created, ATP synthase must process 5 protons.

<h3>Where is ATP synthase found and what does it do?</h3>
  • ADP and phosphate are converted into ATP by the mitochondrial enzyme ATP synthase, which is located in the inner membrane.
  • Protons are transported over a gradient created by electron transfer from the chemically positive to the negative side of the proton, which drives the flux of protons.
<h3>How does photosynthesis's ATP synthase function?</h3>
  • The light-driven production of ATP is catalyzed by the chloroplast ATP synthase, which is activated in the light and deactivated in the dark by redox-modulation via the thioredoxin system.
  • This down-regulation is thought to be crucial for minimizing wasted ATP hydrolysis at night.
<h3>What makes ATP synthase so crucial?</h3>

All cellular functions are powered by ATP, which is constantly used by cells and required for production. About 100 ATP molecules can be produced by each ATP synthase every second.
