Based on the analysis of the provided image, which is a worksheet titled "Active Transport," the task is to label the diagram illustrating this biological process. The diagram shows molecules being moved across a cell membrane with the use of energy.
Here is a breakdown of the key components in the diagram and their corresponding labels:
-
The Purple Structure: This represents the
transport protein (also known as a carrier protein or pump). It is embedded in the cell membrane and facilitates the movement of substances.
-
The Yellow Circles: These represent the
molecules (or ions) that are being transported across the membrane.
-
The Red Curved Arrow Inside the Protein: This indicates the input of
energy, typically from ATP (adenosine triphosphate), which powers the transport process.
-
The Black Arrows Pointing Across the Membrane: These show the
direction of transport. Crucially, the arrows indicate that molecules are moving from an area of lower concentration (fewer yellow circles) to an area of higher concentration (more yellow circles). This movement against the concentration gradient is the defining characteristic of active transport.
In summary, to complete the worksheet, you would label the different parts of the diagram as follows:
- Label the purple structure as "Transport Protein" or "Carrier Protein."
- Label the yellow circles as "Molecules" or "Ions."
- Label the red arrow as "Energy (ATP)."
- Label the black arrows as "Direction of Transport (against concentration gradient)."
This labeling correctly identifies the essential elements of active transport: a specific protein, the substance being moved, the energy required, and the direction of movement against the concentration gradient.
Parent Tip: Review the logic above to help your child master the concept of active transport worksheet answers.
