Answer:
from the intermembrane space to the matrix
Explanation:
In the electron transport chain (ETC), electrons flow from one protein complex to another. However, as this electrons are transfered, protons (H+) is built up from the intermembrane space of the mitochondria to the mitochondrial matrix.
Hence, according to this question, a proton gradient is formed when hydrogen ions (H+) are moving from the intermembrane space to the matrix of the mitochondrial.
<h2>Nuclear Envelope</h2>
Explanation:
- <em>The endomembrane system</em> includes the nuclear envelope, the <em>endoplasmic reticulum, Golgi mechanical assembly, lysosomes, vesicles, just as the plasma layer</em>
- These cell parts cooperate to <em>alter, bundle, tag, and transport layer lipids and proteins </em>
- The nuclear envelope is a double membrane, implying that there are <em>two lipid bilayers</em>
- The nuclear lamina, a netlike cluster of <em>protein filaments, associates the layers of the nuclear envelope</em>
The animals who live in that area will become endangered because their habitat is being heated and they are made for cold only
Answer
Facilitated diffusion is the diffusion
Explanation
Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane
