Unit 1 - Photosynthesis and cellular respiration

Question 1

What is glycolysis and in which part of the cell does it occur (both aerobic and anaerobic)?

Answer 1

Glycolysis is the process in which glucose is broken down to produce energy. This is the first step in the aerobic cellular respiration process, and it occurs in the cytosol.

Question 2

What are the inputs in light dependent reactions?

Answer 2

Water* and light energy*

Question 3

Outputs for light dependent reaction?

Answer 3

Oxygen* (and NADPH, ATP)

Question 4

Inputs for light independent reactions?

Answer 4

(NADPH, ATP) and carbon dioxide*

Question 5

Outputs for light independent reactions?

Answer 5

glucose* and water*

Question 6

What is the relationship between photosynthesis and cellular respiration?

Answer 6

Energy is stored during photosynthesis and released during cellular respiration.

Question 7

What kind of organism produces its own food via the use of inorganic compounds?

Answer 7

Autotroph

Question 8

What is chemosynthesis?

Answer 8

a process carried out by autotrophs in order to create food but different from photosynthesis in the way that sunlight is absent. In this process, glucose is produced using chemicals as an energy source.

Question 9

What is the Kreb’s cycle and in what part of the cell does it take place?

Answer 9

The Kreb’s cycle is the citric acid cycle and occurs in the matrix of the mitochondria.

Question 10

Where does the electron transport chain occur?

Answer 10

The inner membrane of the mitochondria.

Question 11

What are the two fermentation processes that occur for anaerobic cellular respiration to happen and where do they occur?

Answer 11

1) Alcohol fermentation
2) Lactic acid fermentation

Both processes occur in the cytoplasm.

Question 12

How many ATP moles are produced/mole of glucose?

Answer 12

aerobic = 36

Anaerobic = 2

Question 13

What does anaerobic respiration produce in humans and what is it’s function?

Answer 13

Anaerobic respiration serves simply as a backup source of energy when more than usual is required. It is not meant to be sustained for long periods of time, therefore, the lactic acid produced from the reaction builds up in the muscle creating soreness and stopping muscle function. (In humans)

Question 14

What is produced via anaerobic respiration in yeast?

Answer 14

Ethanol and carbon dioxide.

Question 15

Where does glucose come from?

Answer 15

Carbohydrates broken into glucose post digestion.

Question 16

Where does anaerobic respiration occur?

Answer 16

In the cytoplasm.
