What is the name of the molecule that transports oxygen in red blood cells?
The molecule that transports oxygen in red blood cells is called hemoglobin. Hemoglobin is composed of four protein subunits, each containing a heme group that binds to oxygen. This allows red blood cells to carry oxygen from the lungs to tissues throughout the body.
Which molecule rries or binds oxygen?
The molecule that carries oxygen in the human body is hemoglobin, which is found in red blood cells. Hemoglobin binds to oxygen in the lungs and transports it to tissues throughout the body.
What is the term for the overall direction of partial negative charge in a molecule having one or more dipoles?
The term for the overall direction of partial negative charge in a molecule with one or more dipoles is "dipole moment." It is a measure of the separation of positive and negative charges within a molecule and indicates the polarity of the molecule.
How many electrons can a NADH molecule carry?
The electron transport chain is also known as the respiratory chain. NADH carries electrons in the form of hydrogen atoms to the electron transport chain.
How many molecules of oxygen can be transported by one molecule of hemoglobin?
Each molecule of hemoglobin can transport up to four molecules of oxygen. Hemoglobin has four heme groups, each of which can bind to one molecule of oxygen.
What A symporter will transport across the cell membrane.?
2 different ion or molecule in the same direction
Symport uniport antiport have what in common?
Symport, uniport, and antiport are all types of membrane transport mechanisms that facilitate the movement of substances across cell membranes. They involve specific proteins that help transport ions or molecules, but they differ in their processes: uniport transports a single type of molecule in one direction, symport moves two different molecules in the same direction, and antiport transports two different molecules in opposite directions. All three mechanisms are crucial for maintaining cellular homeostasis and supporting various physiological functions.
Which biological molecule transports substances?
Proteins.
What molecule transports amino acids?
tRNA
There is a need for glucose inside a cell but the glucose molecule is too large to pass through the cell membrane. How does the cell solve this problem?
It transports the glucose through transport proteins.
What change takes place in the cell membrane if a signal molecule causes a transport protein to open?
When a signal molecule activates a transport protein on the cell membrane, it undergoes a conformational change that opens a channel or alters its affinity for the molecule it transports. This allows specific substances to move across the membrane, facilitating cellular communication and maintaining homeostasis.
What is a carrier that transports only one type of solute at a time is called?
A carrier that transports only one type of solute at a time is called a uniporter. Uniporters are integral membrane proteins that facilitate the transport of a single type of molecule across cell membranes.
What type of transport requires energy to move molecule?
Active transport requires energy to move a molecule.
What is the active transport and passive transport?
The requirements of passive transport through the cell membrane (phospholipid bilayer) of an animal cell are that the molecule is non-polar or small enough to pass by the non-polar phospholipid tails. This is because, for there to be passive transport, no energy must be used to transport the molecule from outside of the cell to inside.
What molecule transports amino acids to the transcription site?
tRNA, transfer RNA.
Distinguish between the cotransport antiport and symport?
the main feature of cotransport is that neither molecule can move alone; movement of both molecules is obligatory or coupled.. When the transported molecule and cotransported ion move in the same direction, the process is said to be symport. when they move in opposite directions, the process is said antiport
What is it called when transport protein binds with the needed molecule?
passive transport
