The lipid bilayer is a membrane composed of two layers of phospholipids. A phospholipid is a molecule made up of a polar phosphate head and non-polar fatty acid chains.
- The diagram makes reference to the different components of the lipid bilayer.
- The main components of the lipid bilayer are phospholipids and cholesterol.
- The lipid bilayer is also composed of different proteins such as transmembrane integral proteins (channels) and peripheral proteins.
The structures observed in the diagram are as follow:
- Phospholipid molecule (A). Function: structural.
- Polar (hydrophilic) head of the phospholipid (B). Function: stabilize the membrane by its interaction with water.
- Integral glycoprotein (C). Function: signaling pathways and cellular communication
- Oligosaccharide attached to a peripheral protein (D). Function: form the glycocalyx.
- Cholesterol (E). Function: provide fluidity to the lipid bilayer.
- Integral protein (F). Function: signaling pathways and cellular communication.
- Phospholipid bilayer (H-I). Function: Semipermemable barrier that separates the intern cell medium from the surrounding environment.
- Transmembrane integral protein (protein channel) (G). Transport of materials.

Answer: all of these exercise modes, but less likely with low intensity endurance training.
Explanation: exercise increases respiration requirement and therefore oxygen requirement. Energy stores (glycogen) are used first but with then the body needs to maintain energy production at an increased level. There is a limit to how quickly energy can be supplied from respiration and additional energy is generated anaerobically with the by product being lactic acid. An ‘oxygen debt’ is incurred because normal homeostasis requires the metabolism of lactic acid and energy for repair of any cellular damage, requiring oxygen consumption above what is required for normal resting metabolism. It is possible in elite athletes that during low intensity training they may be able to operate aerobically for an extended period.
The structure that traps light energy to make food for the plants is the chloroplast.
<h3>WHAT IS CHLOROPLAST:</h3>
- Chloroplast is a double membrane organelle found in the cells of some eukaryotic organisms e.g. plants.
- Chloroplast is the organelle responsible for the occurrence of the photosynthetic process where light energy from the sun is trapped and used to synthesize glucose/sugars.
Therefore, it can be said that the structure that traps light energy to make food for the plants is the chloroplast.
