It's okay to make errors or have forgotten things. You should do your best to brain-dump everything in your head without resources to improve what you learn from the next slides.

The 'IDENTIFY and LIST' means you can give vocabulary words to help you think. You should be able to reach DESCRIBE, but if you are stuck, start with a vocabulary dump. Or, try writing without the vocabulary if you don't remember it- just describe general processes and use ?? where you've forgotten a word.

IDENTIFY, LIST, DESCRIBE, PROVIDE EXAMPLES, and/or EXPLAIN everything you remember about cell signaling.

Review from Earlier in Semester & Connections:

ratio is too low, as occurs with larger cells, environmental signals could be 'drowned out'. Cell signalling occurs via the same structures that govern this ratio.

Receptors for polar molecules are found in the

, because polar molecules cannot cross the phospholipid tails easily. Receptors for non-polar molecules are found in the

, as these molecules are not opposed by the phospholipid tails.

However,

can afford to be larger than other cells because they have a nucleus and organelles that provide compartmentalization. Compartmentalization in conjunction with complex signalling and feedback mehcanisms allow these larger types of cells to maintain homeostasis.

This is a framework for the first brain-dump question we did.

Sort the terms for signaling into whether they specifically describe endocrine, autocrine, juxta/paracrine signaling, or are generally true or present in all signaling methods. Do not submit when done immediately; instead discuss/recall in more depth what each item means where you can.

See the answer explanation for details about how much you should know for each.

Generally, All Signaling Types

Endocrine

Autocrine

Juxtacrine and Paracrine

Drag and Drop

One form of cellular response is for the cell to begin or stop the production of a protein.

Protein synthesis is also known as the central dogma.

In both eukaryotes and prokaryotes

carries the instructions for protein production.

.

This is a temporary messenger, which in eukaryotes, will leave the

where it was formed. This nucleic acid is capable of leaving and going into the cytoplasm. In prokaryotes, this entire process will happen in the cytoplasm.

In the cytoplasm, a

can convert the message in the RNA to a sequence of amino acids, otherwise known as a

. After folding, this will form a protein.

Describe what appears to be happening in the GIF. You may make inferences based on what you already know, or just use the image and its labels.

We'll then learn a little more and come back to this image.

In multicellular organisms, cells interact and respond to one another to maintain homeostasis for the whole organism. When cell density is high, the growth of other cells is

to prevent crowding. In contrast, when there is an injury, cell growth is

so that the body can replace the dead cells.

As part of some signaling pathway responses, transcription factors called

factors stimulate the production of more cell structures to prepare for division. These factors should be produced and used by healthy cells, and cells have ways of knowing whether they are healthy or not.

Cells check the quality of their

before beginning the cell cycle to make new cells, because if this molecule has been damaged significantly, the daughter cells won't have the necessary instructions to make functional proteins.

A cell determined to be unhealthy should receive a signal to die. This process is called

. Cells that ignore the death signal are cancerous.

Paste your writing from earlier, and add some details based on what we just learned to describe the cell cycle.
