Photosynthesis and Cellular Respiration Lecture

These flashcards cover key concepts from lectures on photosynthesis and cellular respiration, as well as topics related to cell division and genetics.

What is the general chemical equation for photosynthesis?

6CO2 + 6H2O + light energy --> C6H12O6 + 6O2

What are chemical molecules that can absorb light called?

Pigments

Where does O2 gas produced in photosynthesis come from?

When water is split to give electrons to the photosystems

What is the main purpose of the Calvin Cycle?

To build sugar molecules

What is the final product of photosynthesis?

Glucose (C6H12O6)

During which stage of cellular respiration is ATP produced?

Electron transport chain

What happens during glycolysis?

Glucose is split in two

How much ATP is usually produced from one molecule of glucose using cellular respiration?

32 ATP

What is the purpose of fermentation in the cell?

To regenerate NAD+ for glycolysis when no oxygen is present.

What is cancer related to in cell division?

Out of control growth and division caused by failed cellular mechanisms.

What happens during crossing over in meiosis?

Chromosome pairs trade pieces of DNA with each other.

What is the difference between meiosis and mitosis?

Meiosis produces 4 non-identical cells, while mitosis produces 2 identical cells.

What is Mendel's law of segregation?

The two alleles for the same gene separate during gamete formation.

What is the job of DNA Helicase during DNA replication?

It unzips/separates the two old strings of DNA for copying.

What is the process of manufacturing proteins using RNA code called?

Translation

What is the job of tRNA?

To deliver amino acids to the ribosome.
