Soil creep is the downward movement of soil, on a slope, caused by the force of gravity. A slow deformation of soil material over a prolonged period of time, from pressure and stress. Creep occurs when the friction from materials resisting gravity move against each other. Slope is a key cause of soil creep.
Answer:
A. play a role establishing and maintaining membrane lipid asymmetry
Explanation:
Proteins that move move certain phospholipids between leaflets are transmembrane proteins via "flip-flop" transition have also the possibility to maintain membrane lipid asymmetry. There are few types of such proteins:
- flipases-move lipids from the exterior to the interior side of the membrane, energy required
- flopases-move lipids in reverse comparing to flipases, energy required
- scramblases-no energy required, bidirectional
Because of the action of those proteins, cytosolic side of plasma membrane differs from exoplasmic side (asymmetry).
At the inner mitochondrial membrane<span>, a high energy electron is passed along an electron transport chain. The energy released pumps hydrogen out of the matrix space. The gradient created by this drives hydrogen back through the </span>membrane<span>, through ATP synthase.</span>
Well lipids have phospholipids sticking out while carbs are connected like this i don’t rlly know how to explain it better but here is a pic that can help
