Q

Explain the equation for photosynthesis?

A

6CO2+6H2O➡️➡️➡️➡️➡️C6H12O6+6O2 there are lots of arrows because lots of steps are involved in photosynthesis

Q

What are the differences between the light dependent and light independent reactions?

A

Light dependent captures sunlight and takes place in/across the thylakoids membrane and needs water and sunlight. Light independent uses the energy from light dependent and is in stroma and needs carbon dioxide

Q

Steps in light dependent reactions?

A
  • energy is absorbed from sunlight
  • water molecules broken down
  • H+Ions transported thylakoid membrane
  • energy from sunlight absorbed
  • NADPH produces from added electrons from NADP+
  • H+ions diffuse through protein channel
  • ADP changed to ATP when H+ flow through ATP SYNTHASE
16
Q

What’s function of Calvin Cycle?

A

Use carbon dioxide energy from ATP and NADPH to make simple sugars

17
Q

What is the electron transport chain?

A

Series of proteins in thylakoid membrane

18
Q

What is cellular respiration?

A

Releases chemical energy from sugars and other carbon based molecules to make ATP when oxygen is present

19
Q

Why is cellular respiration an aerobic process?

A

It needs oxygen to take place

20
Q

Where does cellular respiration take place?

A

Takes place in the mitochondria

21
Q

In what two ways does cellular respiration seem to be the opposite of photosynthesis?

A

Chemical equation is reverse of each other and chloroplasts absorb energy from sunlight to build sugars and mitochondria releases chemical energy to make ATP

22
Q

In which two parts of the mitochondria does cellular respiration take place?

A

Matrix and inner mitochondrial membrane

23
Q

Chemical equation for cellular respiration?

A

C6H12O6+ 6P2➡️➡️➡️➡️6CO2+6H2O

24
Q

What is the Krebs Cycle?

A

Produces molecules that carry energy to the second part of cellular respiration

25
Q

What is the function of glycolysis?

A

To break down glucose to make pyruvate and to make 2 ATPs

26
Q

What happens to the molecules formed during glycolysis when oxygen is available?

A

It moves on to the Krebs cycle to be further broken down

27
Q

What is met by the net gain of 2 ATP molecules in glycolysis?

A

Overall only 2 molecules of ATP are made in glycolysis

28
Q

What is the function of Krebs cycle?

A

Transfer high energy electrons to molecules that carry them to the electron transport chain

29
Q

Where is the electron transport chain in cellular respiration located?

A

In and across the mitochondrial membrane

30
Q

What is the function of the electron transport chain?

A

Pump hydrogen ions against concentration gradient and across inner mitochondrial membrane with elections from NADH AND FADH2 and produce ATP

31
Q

Why is oxygen needed for cellular respiration?

A

Needed to pick up electrons that have gone through the chain

32
Q

What is the importance of fermentation?

A

It allows glycolysis to continue even without oxygen

33
Q

What is the function of fermentation?

A

Removed electrons from NADH molecules and recycles NAD+ molecules for glycolysis

34
Q

When does fermentation take place in your muscle cells?

A

When a molecule of glucose has just been split but oxygen isn’t available and you’re working hard

35
Q

Why is fermentation an anaerobic process?

A

Doesn’t require oxygen

36
Q

How is fermentation involved in the production of ATP?

A

It supples a steady supply of NAD+ so ATP can be produced.

37
Q

What is Latic acid

A

C3H6O3
