Resperation

Question 1

Why do organisms need energy

Answer 1

We need them to carry our life process.Some get there energy from sun (producers) like plants and others from food (consumers)

Question 2

What is resperation

Answer 2

It’s a series of enzyme controlled activities to release the chemical energy stirred in glucose

Question 3

What is the classic aerobic respiration formula

Answer 3

Glucose + oxygen - co2 water and lots of energy

Question 4

What is the formula for fermentation in plant and yeast when there is no oxygen

Answer 4

Glucose- co2 ethanol and littke energy

Question 5

In animal fermentation equation

Answer 5

Glucose - lactate and a little energy

Question 6

What is ATP

Answer 6

The meaning is adenine troposphere
It is an energy rich compound that when broken gives energy.It allows living processes to occur.It is made of an adenosine attached to three phosphate.When the third phosphate bond is broken it gives out energy as its an energy rich bond

Question 7

The equation for ATP

Answer 7

ATP- ADP + Pi + energy

Question 8

What happens to muscles when the contract

Answer 8

Decrease in length

Question 9

Why do we calculate percentage in this experiment

Answer 9

Becuase the starting length/ measurement is different

Question 10

What happens as the atp concentration increases in the muscle issue

Answer 10

The muscle contracts more decreasing in length

Question 11

Explain the glycolysis experiment this is the starter for both fermintion and aerobic resperation

Answer 11

This takes place in the cytoplasm.The glucose splits into 2 molecules of private ad yields 2 molecules of ATP on the way

Question 12

How is the process of aerobic resperation continued

Answer 12

When oxygen is present the private molecules move nto the mitochondria (the site of aerobic resperation).By a series of ENZYME CONTROLLED steps the pyruvate breaks into co2 and water.and this yields many molecules of atp (36).This is the complete breakdown of glucose and it yield many molecules of atp.

Question 13

The summary of aerobic resperation is

Answer 13

In cytoplasm In mitochondria
Glucose ————2 molecules pyruvate OXYGEN HERE———- CO2 and water
2 ATP 36 ATP
Lots of energy

Question 14

Explain fermentation pathways

Answer 14

Since there is no presence of oxygen the glucose is only partially broken down.Glycoliss happens in the cytoplasm and finishes their.The process of fermentation only yield 2 molecules of atp.

Question 15

How are fermentation pathways like in animals
(Oxygen depth)

Answer 15

During intense activity like being at the gym.The oxygen amount needed might not be met.So our body carries out fermentation.The product of fermentation in animals is lactate and little energy.This lácate causes pain resulting in muscle fatigue.To remove this discomforting lácate we need oxygen.When this happens it is known as an oxygen dept.The oxygen dept will go away after some rest.

Question 17

Fermantaion in plants and yeast

Answer 17

Yeast cells deprived of oxygen and plant cells that have been drowned in water (water logged) cannot do aerobic resperation o they do fermentation.The glucose is broken down into 2 molecules of pyruvate and 2 molecules of ATP.This pyruvate will then break down into CO2 and ethanol

Question 18

Explain the experiment where the yeast cell is put in a beaker

Answer 18

This process is feremention.Yeast is put into a beaker with only glucose prestan and no oxygen.The products are co2 etanol and heat in this instance.This is used in making alcohol and bread making.We take out all oxygen in the glucose and yeast solutions and we put oil to stop any oil coming in.The ethanol is produced.And we can see fr that co2 is produced as it turns lime water cloudy.

Question 19

Give all info about mitochondria

Answer 19

This is the site of aerobic resperation.The Inter membrane is folded to allow max surface area from aerobicb. Resperation.
Cells that require a lot of energy need to have a lot of mitochondria
