energy for exercise

Question 1

What is Atp?

Answer 1

Made up of one adenosine molecule and 3 phosphate groups held together by bonds of chemical energy. only immediately usefu form of energy stored in our bodies- readily available as its stored in the muscle cell

Question 2

What is at pase?

Answer 2

Breaks down the bond between the last 2 phosphate groups which releases energy that us used to make the muscle cell contract and the movement

Question 3

What is a coupled reaction?

Question 20

What are the specific stages for glycolytic system?

Answer 20

Glucose undergoes aerobic glycolysis

pyretic acid/without 02- lactic acid

Answer 23

High intensity

Question 24

What is the duration of the system for glycolytic system?

Answer 24

Up to 3 minutes

Question 25

What are the strengths for glycolytic system?

Answer 25

No delay for 02 Large fuel stores in liver, muscles and blood stream provides energy for high- intensity activities for up to 3 minutes lactic acid can be recycle into fuel for further energy production

Question 26

What are the weaknesses for glycolytic system?

Answer 26

Fatiguing by product lactic acid reduces ph and enzyme activity relatively low atp yield and recovery can be length

Question 27

What type of reaction is the aerobic system?

Answer 27

aerobic

Question 28

What type of chemical/ food is used for aerobic system

Answer 28

glycogen/ glucose or fat

Question 29

38 Moles of Atp

Question 32

What are the specific stages of aerobic system

Answer 32

aerobic glyolysis Krebs cycle electron transport chain

3 minutes onwards

Question 37

What are the strengths for aerobic system?

Answer 37

Large fuels: triglycerides, free fatty acids (FFAs) glycogen and glucose High atp yield and long duration of energy production no fatiguing by products

Question 38

What are the weaknesses with aerobic system?

Answer 38

Delay for oxygen delivery and complex series of reactions | slow energy production limits activity to sub- maximal intensity

Question 39

What is the energy continuum?

Answer 39

The energy continuum refers to the contribution that the different energy systems make to the production of energy,

Question 40

What is the intermittent exercise?

Answer 40

The intensity alternates, the threshold of any energy system is the point at which it is unable to provide energy nd therefore switches to another system

Question 41

What happens in recovery periods?

Answer 41

Revoery periods allow for rehurtation and glycogen replacement. Aerobic activities rely o atp-pc, although cc runs out quickly it resynthises quick, Oxygen stored in myoglobin can be fully replenished in 3 minutes

Question 42

What is a v02 max?

Answer 42

Maximum volume of oxygen inspired, transported and utilised per minute during exhaustive exercise

Question 43

What is the fitness level?

Answer 43

Once blood lactate values go above 4mmol, the onset of blood lactate accumulation (OBLA) has been reached The point will be dependent on the aerobic fitness of the performer, may be about 50% of their v02 max. due to increased ability to tolerate lactic acid and to remove waste products and supply oxygen to working muscles.

Question 44

What is the recovery process?

Answer 44

Help the body return to its pre-exercise, energy is required Continused aerobic production fulfils this additional energy requirement. (excess post-exercise oxygen consumption) 1) fast alactacid component of recovery 2) slow (lactacid) component of recovery

Question 45

What is the fast a lactacid component of recovery?

Answer 45

phosopohcreatine stores restored 3 minutes pc stores to fully recover replenishment of blood and muscle oxygen- within the first minute, oxygen resaturates the blood stream, associating with haemoglobin and within 3 minutes restores the oxymygolbin link in the muscle cells

Question 46

What is slow lactacid component?

Answer 46

Elevated ventilation and circulation, post exercise respiratory rate, depth and hr remain elevated. these gradually decrease to resting levels to maximise delivery of 02 and the removal pf by-products
