Q

What is Cellular Respiration?

A

When you take glucose and create ATP.

  • When cells need energy, for specific method, it must be provided in the more directly usable form of ATP.
  • When you release energy needed for all kinds of worrk.

Q

What are the functions requiring ATP?

A
  • motion: causes various specialized fibres within cells to contract causing movement of the cell movements within the cell.
  • transport of ions and molecules: causes muscles fibres to contract.
  • building molecules - provides the energy needed to form many large molecules.
  • switching reactions on or off - alters or changes the shape of a molecule, which alters the function of the molecule.
  • bioluminescence - reacts with a molecule called luciferin and oxygen.

Q

What does aerobic cellular respiration require?

A

It requires oxygen

18
Q

What does anaerobic cellular respiration not require?

A

It doesn’t require oxygen

19
Q

What is Glycolysis?

A

It is when you harness energy which glucose molecules are broken into 2 pyruvate molecules.

Another word for “sugar splitting”

20
Q

What does Glycolysis not need?

A

It doesn’t need oxygen. Also it an anaerobic process.

21
Q

Where does Glycolysis take place in?

A

In the cytoplasm

22
Q

What are the 10 reactions in glycolysis?

A

2 ATP molecules are utilized

4 ATP molecules are manufactured

23
Q

What are the 4 stages of Aerobic Cellular Respiration?

A
  1. glycolysis
  2. pyruvate oxidation
  3. The Krebs Cycle
  4. The Electron Transport Chain
24
Q

What is the Anaerobic Cellular Respiration?

A

Takes place in the absence of oxygen.

25
Q

What is Mitochondria?

A

Round or sausage-shaped organelles that usually scattered throughout a cell’s cytoplasm.

26
Q

What is Mitochondria Matrix?

A

Protein-rich liquid which fills the innermost space of a mitochondrion.

27
Q

What is Intermembrane Space?

A

Fluid-filled space among the inner and outer mitochondrial membranes.

28
Q

What are the 2 processes that eukaryotes use?

A
  • Lactic Acid Fermentation

- Alcohol Fermentation

29
Q

What is Alcohol Fermentation?

A

The form of fermentation happening in yeast in which NADH passes it hydrogen atoms to acetadehyde, generating carbon dioxide, ethanol and NAD+.

30
Q

What is Lactic Acid Fermentation?

A

A form or shape of fermentation happening in animal cells in which NADH transports its hydrogen atoms to pyruvate, regenerating NAD+ and lactic acid.

31
Q

What is Maximum Oxygen Consumption VO2 max?

A

It’s a measure of a body’s capacity to generate the energy needed for physical activity.

32
Q

What is Lactic Acid Threshold?

A

It’s the value of exercise intensity at which blood lactic acid concentration starts to increase sharply.

33
Q

What is Electron Transport?

A

it releases relatively large amounts of energy.

34
Q

What is used to pump H+ ions

A

Energy gone by the electron pair during the electron transport.
