1. The chemical labelled 1 is secreted by the sender cell in a cell signaling process called as
ligands
receptors
activators
effector molecules

2. The target cell has proteins that specifically binds with ligands and initiates a cellular response; labelled 2 is
receiver
receptor
coreceptor
receptor ligand complex

3. In cell signaling, the first stage is the binding of the signaling molecule (ligand) to the cell surface receptor or receptor inside the cell; labelled 3 is called
Ligand binding
Reception
Cellular response
Cell activation

4. The binding of ligand to the receptor causes a confirmational change in the receptor that initiates a sequence of reactions activating many relay molecules finally activating the target molecule for cellular response. The second stage of cell signaling labelled 4 is called
Transduction
Reception
Transformation
Intracellular activation

5. In the final stage of cell signaling; the target molecule triggers a cellular response in target cell by gene expression leading to cell division, activation of enzymes etc; labelled 5 is called
Transformation
Cellular response
Gene expression
Intracellular activation

6. In this type of signaling labelled 6; Cells respond to the signal produced by themselves called as
Endocrine signaling
Autocrine signaling
Paracrine signaling
Direct signaling

7. Signaling type labelled 7 are communication junctions called gap junctions in animals and plasmodesmata in plants. This type of signaling is called
Endocrine signaling
Autocrine signaling
Paracrine signaling
Direct signaling

8. Signaling molecules produced by the sender cell induces cellular responses in neighbouring target cells. This type of signaling labelled 8 is called
Endocrine signaling
Autocrine signaling
Paracrine signaling
Direct signaling

9. Signaling molecules often hormones are secreted by endocrine cells carried through the blood stream to distant target cells a type of cell signaling labelled 9 is
Endocrine signaling
Autocrine signaling
Paracrine signaling
Direct signaling

10. The above four types of signaling is based on
distance travelled by the ligands or signaling molecule
type of the receptors
type of tissues
all of these
