The main component of cell membranes is phospholipids - which form a bilayer (with polar heads facing outwards and tails facing inwards).

Where in the cell is ATP used for cellular activities?
ATP or adenosine triphosphate is the form of energy used by the cell for most of its functions. It is used in the nucleus for DNA replication and RNA transcription. It is used for muscle contraction. It is also used for active transport across the cell membrane.
What is used for cell recognition and communication?
Proteins embedded in the cell membrane.
Outline four functions of proteins within the cell membrane?
There are four functions of proteins within the cell membrane. The four functions of proteins are active transport, cell recognition, cell communications, and are used as enzymes in the cell membrane.
What does the cell membrane in an animal cell do?
the cell membrane that surounds an animal cell is used to protect the internal cell from chemical "intruders". also it is used separate the cell from the the extracellular membrane. it keep it's cytoplasm separate from the extra cellular membrane.
What form of transport is used by the cell membrane to speed up the intake of glucose?
active uptake, which requires energy and protein carriers in membranes
What type of molecule can be used as a tunnel to move compounds across the cell membrane?
Lipid molecule
Which organic molecule is used to build the majority of the cell membrane?
Phospholipids.
What used a protein to move a molecule across a cell membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
What molecule is used to transport oxygen act as an enzyme transport materials across the cell membrane and forms the filaments of muscle?
haemoglobin
What molecule is used to transport oxygen and act as an enzyme and transport materials across the cell membrane and forms the filaments of muscles?
Protein.
What is a molecule used by glucose as a piggyback into and out of the cell in the process of active transport?
The glucose transporter is a membrane bound protein that binds to glucose and mediates it's transport into or out of the cell.
Which type of transporters is used to move a molecule from a region of low concentration traction to a region of high concentration?
protein molecules in the cell membrane
Which row in the chart below best the active transport of molecule X through a cell membrane?
Low concentration to high concentration; ATP is used
What happens to the pocket in the cell in the membrane when it breaks loose from the membrane?
Usually, the membrane will burst and let its contents out into the cell membrane and get used up.
Which row in the chart below best describes the active transport of molecule X through a cell membrane?
Low concentration to high concentration; ATP is used
What is bigger an animal cell or a molecule?
An animal cell by a trillion times over. A single molecule would be a single tail of a hydrocarbon which is used to make the lipid bilayer. This is made up of millions of phospholipids. Each has a tail and this is only the outer membrane of the cell which contains a huge amount of material.
What cell part is used to describe the outer edge of a frog blood cell?
Cell membrane
