3 organic molecules
Carbohydrates( glucose)
Lipids( cholesterol)
Protein(Beans)
Lipids function
There are different tyeps of lipids with theire own functions such as phospolipid which helps with structure and allowing certain things in the cell
Function of protein
Proteins usually helps with transpotation such as hemoglobin and protein carriers along with channels helps transport ions and nutirents
Carbohydrate roles
: particularly glucose, serve as a primary energy source for cells. They are broken down during cellular respiration to produce ATP, the energy currency of the cell.
Saturated Fats
saturated fats contain one or more double bonds in their fatty acid chains, which introduces kinks that prevent the molecules from packing tightly.
Solid room temp
Lower LDL
Unsaturated Fats
unSaturated fats have no double bonds between carbon atoms; all carbon atoms are fully “saturated” with hydrogen atoms.
Liquid in room temp
High intakes raise LDL
what are the 4 components of the cell membrane
Phospolipids
protein
cholesterol
Carbohydrates
How are phospolipids arranged in the membrane
tail being the hydrophobic side and the head being the hydrophilic and the tail being the Hydrophobic side Forming 2 layers of Phospholipids with the tails facing each other to maintain structure and balance
How are protein arranged
Snuggled within the Phospholipid bilayer it performs different functions such as Transporting and signaling
how are cholesterol arranged
Scattered within the bilayer it helps with the fluidity of the membrane
how are carbohydrates arranged
Attached to proteins or lipids and functions for recognition and signaling
How does cholesterol help with fluidity
When membrane gets too fluid or rigid it helps to balance especially how its snuggled in between the lipids
