Quick Answer: Which Energy System Is The Most Efficient?

What are the 3 main energy systems?

Like most mammals, you generate energy via three systems: phosphagen (ATP-PC), glycolytic, and oxidative (see figure 2.1).

All three energy systems are engaged during all forms of physical activity.

However, the extent to which each one is involved varies depending on the duration and intensity of the activity..

What energy system is used first?

The first two energy systems are anaerobic, meaning they do not require oxygen. The aerobic energy system must have oxygen or the entire process will slow down and potentially stop completely. The oxygen needed by this system is provided by the cardiovascular and respiratory systems via blood flow to the tissues.

Which energy system is the slowest to produce ATP?

During maximal exercise, the rate of glycolysis may increase to 100 times the rate at rest. Produces ATP at the slowest rate compared to the anaerobic systems.

Which stage produces the most ATP?

Krebs cycleThe Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria.

What is the process that produces ATP?

cellular respirationThe process human cells use to generate ATP is called cellular respiration. It results in the creation of 36 to 38 ATP per molecule of glucose. It consists of a series of stages, beginning in the cell cytoplasm and moving to the mitochondria, the “power plants” of eukaryotic cells.

What energy system that breaks down carbohydrates using 1 to 2 minutes?

Lactic Acid energy system starts to feed the muscle energy if the activity is longer then 6 seconds but less then two minutes. The body goes through a chemical process called glycolysis (breaking down of carbohydrates into glycogen) which is a way of producing energy for the muscles so they can continue working.

What energy system that requires carbohydrates using 1 to 2 minutes of energy?

Lactic Acid System: Carbohydrate Use Only The second energy system, the lactic acid (or glycolysis) system, supplies the additional energy for activities that last longer than 10 seconds and up to about 2 minutes.

Which energy system produces the most ATP?

aerobic systemThe aerobic system produces far more ATP than either of the other energy systems but it produces the ATP much more slowly, therefore it cannot fuel intense exercise that demands the fast production of ATP.

What are the three stages where glucose is transferred to ATP?

All of them burn glucose to form ATP. The reactions of cellular respiration can be grouped into three stages: glycolysis, the Krebs cycle (also called the citric acid cycle), and electron transport. The figure below gives an overview of these three stages, which are also described in detail below.

Which type of cell respiration produces the most ATP?

electron transport chainThe highest ATP yield during respiration occurs during the electron transport chain (32 ATP). This occurs when electrons flow through the transport chain, which causes protons (positively charged Hydrogen) to be pumped from the mitochondrial matrix to the inner-membrane space. This causes a proton gradient to form.

Which energy system uses oxygen?

aerobicEnergy system one – aerobic The aerobic energy system is also known as the oxygen energy system and it uses both carbohydrates and fat in a slow energy burn. The aerobic energy system is the most complex of the three using oxygen to create something called glycolysis and, ultimately, produce that all-important ATP.
