What are material need for cellular respiration?
glucose and oxygen
What gas do you need more of during exercise?
During exercise, your body needs more oxygen to supply to your muscles. This is because oxygen is essential for the process of generating energy through aerobic metabolism. Therefore, increasing your oxygen intake through respiration is important to support your muscles during physical activity.
What products of photosynthesis do animals need to survive?
Oxygen is produced as a by-product of photosynthesis.
What does cellular respiration need in order to begin?
Glucose and oxygen
During excersise why does breathing rate increase so quickly?
Because your muscles need more oxygen, hence you hyperventilate.
What must the muscle cells be provided with in order for muscle fatigue to stop?
The fatigued muscles would need more glucose and oxygen.
Why do you take in more oxygen when you are exercising?
Your muscles require more energy when they are active during exercise. Muscles in your body metabolise glucose (sugar) in your bloodstream, breaking it down and taking it in to generate a high energy molecule known as ATP, which is essential for a cells functioning. Part of this process requires oxygen to fully break down the glucose-so when you need more energy metabolised, you'll need more oxygen too. If you don't get enough oxygen, your muscles will not be able to fully break down available glucose, they'll become fatigued and produce lactic acid instead- giving you a sore welling.
How do blood and oxygen work together in the body when you are running?
When you are running, your muscles are working extra hard. Therefore, they need more oxygen and glucose than normal, since it is the chemical reaction between these two that produces energy for work. The blood is pumped to the lungs for more oxygen and to the liver for more glucose. (Glucose is stored in the liver.) Blood flow to the working muscles is increased in order to deliver these two, and to carry away carbon dioxide and heat that are produced as wastes.
How do you get energy fast?
When you are exercising you use your energy up and that's why you breathe fast but in order to get more energy you need more oxygen and glucose. To get more oxygen you need to breathe faster and to get more glucose you need to eat or drink something containing sugar, because glucose is a sugar.
Why does heart rate increases?
because you need more oxygen to be delivered to the muscle and more waste to the lungs. when you are exercising your muscles need oxygen so the blood stars pumping faster to get the oxygen to the muscles.
Why do you breath very quickly after exercise?
Because when you work your muscles they need more oxygen, and to get more oxygen you need to breathe more often.
What is the process where the muscles need oxygen?
if the working muscles do not have enough oxygen, then the process is anaerobic respiration where the glucose in the cells is creating lactic acid as it is not reacting with the oxygen needed like it would if the body was respiring normally then it would be aerobic respiration
Why does the heart beat faster when exerciseing?
As you exercise, the muscles need more oxygen to work. The heart beats faster to get the oxygenated blood from the lungs to the muscles. The harder you exercise, the more oxygen the muscles need, the faster the heart beats.
Why do we become short of breath?
Your muscles use oxygen that's extracted from the air by the lungs and transported to the muscles by the blood. When you begin to move your muscles will need more oxygen, so you need to breathe faster in order for the lungs to be able to pick up more oxygen from the air.
How do muscles get energy when there is low levels of oxygen?
Muscles can generate energy through anaerobic pathways, such as glycolysis, which can produce ATP without the need for oxygen. During low oxygen levels, glycolysis helps break down glucose to provide energy for muscle contraction. However, this process can lead to the accumulation of lactic acid and fatigue.
What two things do muscles need?
nutrition and oxygen
What happens to the heart when you exercise?
Muscles need more oxygen and glucose during exercise.They dilate their arteries to receive more blood . At the same time,working muscles push more blood in the veins to the heart.This increases the volume of blood reaching the heart.The heart therefore has to pump harder and faster.
