The main molecules are lipids (with different fatty acid chains depending upon the kind of membrane), proteins (that can be associated with the external part of the lipid bilayer, embedded in the lipid bilayer and those associated with the interior part of it ), and sugars (complex polysaccharides that can be part of the docking site of protein receptors, to have function of blood types, or to be recognized by antibodies).

In addition to phospholipids, cholesterol is a key organic molecule found in cellular membranes. Cholesterol helps to stabilize membrane fluidity, making membranes less permeable to very small water-soluble molecules that might otherwise pass freely through. It also contributes to the structural integrity of the membrane, allowing for proper functioning of membrane proteins and overall cellular health.

Three different types of molecules appear in the membrane of a cell. These molecules are lipids, proteins, and carbohydrates.
You would expect to find proteins, enzymes, lipids, carbohydrates, and metabolites among the other cellular molecules released into the solution once the membranes have dissolved. These molecules are essential components of the cell and play various roles in its function and structure.
A vacuole does not typically function to "transport molecules." Instead, its primary roles include storing molecules, digesting certain substances, and sometimes fusing with other membranes to release or modify contents. Transport of molecules is generally handled by other cellular structures and mechanisms, such as vesicles and the endoplasmic reticulum.
Membranes participate in intercellular signaling by containing receptors that can detect signaling molecules from other cells. These receptors can trigger a cascade of intracellular events that lead to a cellular response. Additionally, membranes can also release signaling molecules themselves through processes like exocytosis or shedding of vesicles.
The temporary storage of energy in ATP molecules is part of cellular respiration. During cellular respiration, glucose is broken down in a series of steps to produce ATP, which is used as the main energy source for cellular activities.
Membrane proteins play crucial roles in cellular function and structure by facilitating the transport of molecules across cell membranes, serving as receptors for signaling molecules, and helping to maintain the integrity and stability of the cell membrane.
Small uncharged polar molecules play a crucial role in cellular processes by helping to transport substances across cell membranes, regulate cell signaling, and participate in metabolic reactions within cells.
38around 29 to 30 ATP per glucose molecules realistically speaking. Some say higher but this is unlikely due to leaky membranes.
