Answer:
Lipid bilayer can be defined as a polar membrane, which composes two layers, made up of lipid molecules. It shows both hydrophobic (due to non-polar tails of lipid molecules) and hydrophilic (due to polar heads of lipid molecules) nature, and hence is known as of amphipathic nature.
Lipid bilayer shows selective permeability as not all molecules can cross the lipid bilayer. It can pass non-polar, small, uncharged molecules due to its hydrophobic core, such as oxygen, water, urea.
On the other hand, polar, large, or charged molecules, such as glucose, amino acids, and ions cannot pass through lipid bilayer. These molecules require transport proteins for their transport, which are embedded in lipid bilayer.
he lipid bilayer has unique properties. They are formed in sheet-like structures that contain both a hydrophilic and a hydrophobic moiety. The membrane is composed of lipids and proteins and sometimes even carbohydrates. There are two different membrane proteins in the lipid bilayer.
Answer:
a. Rotation of the shaft protein driven by the proton gradient
Explanation:
The F1 portion of ATP synthase is hydrophilic and responsible for hydrolyzing ATP. The F1 unit protrudes into the mitochondrial matrix space. ... γ subunit allows β to go through conformational changes (i.e., closed, half open, and open states) that allow for ATP to be bound and released once synthesized.
The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.
Answer:
it is D because if the parasite feeds on blood not enough blood will make the hosts heart no pump enough blood and eventually die
its asking for you to check the box if the item is preset in the cell hint: eukaryotic cells have a nucleus so you would say yes in the box. but since prokaryotic cells don't have a nucleus say no in the box
They have half as many chromosomes as the rest of the cells (so that when they meet, the chromosomes will be combined to make a different set)
