What is the path of H+ions through the thylakoids
Mariana [72]

Answer and Explanation:

Hydrogen ions in the thylakoid space form an electrochemical gradient because of the difference in the concentration of protons (H+) and the difference in the charge across the membrane that they create. This potential energy is stored as chemical energy in ATP through chemiosmosis. The hydrogen ions are allowed to pass through the thylakoid membrane through an embedded protein complex called ATP synthase. Energy from the electron fuels membrane pumps that actively move hydrogen ions against their concentration gradient from the stroma into the thylakoid space. The photon causes an electron in the chlorophyll to become excited.

Write 5 statements to compare eukaryotic and prokaryotic cells
Ilya [14]

Answer:

Explanation:

Hi there!

We can compare prokaryotic cells and eukaryotic cells in following points:

• The prokaryotic cells are simple and primitive type of cells whereas •Eukaryotic cells are complex and advanced cells.

•The DNA is small and circular in prokaryotic cells whereas the DNA is large and linear in eukaryotic cells.

•In prokaryotic cells 70s type of ribosome is found in cytoplasm but in Eukaryotic cells both 70s (inside cell organelles) and 80s (in cytoplasm) are found.

• In prokaryotic cells cellular respiration takes place through cell membrane but in eukaryotic cells cellular respiration takes place through mitochondria.

Hope it helps!
