Flashcards for Photosynthesis, Cell Division, and Gene Expression

Thylakoids

The location of the light reactions of photosynthesis.

Oxygen

Plants produce this during photosynthesis in Photosystem II.

Chlorophyll

A photon of light directly causes this to become excited and lose an electron during the light reactions.

Water

Photosystem II gets electrons from this molecule

Electron transport chain

Photosystem I gets electrons from this structure

Only ATP is needed

Cyclic electron flow occurs through photosystem I under these circumstances.

ATP and NADPH

The products of the light-dependent reactions in photosynthesis.

Sugar

A product of the Calvin Cycle.

Less sugar gets made

One outcome of photorespiration.

Stomata

The name for the holes in plant leaves that allow oxygen to diffuse out.

Breast

The type of cancer the course focuses on.

Yeast

The organism scientists won the Nobel prize for discovering cell cycle regulation in.

Orthologs

Eukaryotes have these to regulate the cell cycle.

Platelets

The target of PDGF.

Platelets

The source of PDGF.

Kinase

The type of protein that phosphorylates target proteins.

Cell cycle

What increases in response to PDGF?

Kinase

The type of receptor PDGF uses.

Bone

Location of megakaryocytes.

START

The point in the cell cycle regulated by PDGF.

Three

Number of nucleotide letters in each codon.

A site

Where aminoacyl tRNA first binds to the ribosome.

P site

Where the growing protein chain is positioned during translation.

Reaching a stop codon

The last step in translation.

200 amino acids

The length of protein translated from an mRNA coding region of 600 nucleotides.

T

A nucleotide not found in RNA.

Three nucleotide deletion

The mutation in the coding region least likely to cause a problem.

Transcription factor

What activates insulin gene expression?

Transcription unit

What changes when gene expression occurs?

Coding region

In sickle cell anemia, where the mutation is located in the gene.
