What factors might affect the process of cellular respiration?

The glucose is broken apart, producing energy, stored in the form of ATP, and carbon dioxide and water as waste products. If the oxygen supply becomes scarce, or is nonexistent, the cell switches to anaerobic fermentation to produce energy. This method is faster, but not as productive as aerobic respiration.

We’ll first review what cellular respiration is, and then explore how three factors affect it: temperature, glucose availability, and oxygen concentration.

What Is Cellular Respiration? Right now, you’re probably not running or jumping around, but you’re still using energy.

Temperature.

Glucose Concentration.

Aerobic cellular respiration rates vary according to three main factors: the amount of nutrients available to the cell, the specific type of cell and the ambient temperature. All three factors affect the rate at which respiration takes place.

The eight environmental factors effecting the rate of respiration are: (1) Oxygen Content of the Atmosphere (2) Effect of Temperature (3) Effect of Light (4) Effect of Water Contents (5) Effect of Respirable Material (6) Effect of Carbon Dioxide Concentration (7) Protoplasmic Conditions and (8) Other Factors.

This is due to the fact that as more energy is used during exercise, more oxygen is required in the human body to fuel cellular respiration. Cellular respiration produces energy in the form of ATP and releases CO2 is a byproduct.

Blood pH — a reflection of its relative acidity or alkalinity — also influences respiratory rate. Activity level and the presence of drugs or alcohol are other important factors that affect respiratory rate.

It is necessary for germinating seeds to undergo cellular respiration in order to acquire the energy they need for growth and development. Unlike their mature relatives, seeds do not yet have the necessary photosynthetic abilities needed to product their own energy sources.

Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate.

Factors affecting photosynthesis. Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide.

The potential of NADH and FADH2 is converted to more ATP through an electron transport chain with oxygen as the “terminal electron acceptor”. Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation.

Enzymes play a large part in respiration as it helps to catalyse the reaction. Enzymes are affected greatly by pH. Enzymes are said to have an optimum pH. This means that when the pH is greater than the optimum, the enzyme will be denatured and no longer be able to catalyse the reaction.

There are many factors can affect ATP production, one of which is temperature. When temperature increases, rate of respiration increases as well because the heat speeds up the reactions which means kinetic energy is higher. When temperature decreases, in order to conserve energy, cellular processes slow down.

The by-products of the fermentation process are carbon dioxide and ethyl alcohol (ethanol). A yeast population is affected by a number of factors, the control of which is essential for optimal activity. These factors include pH, temperature, nutrient availability, and the concentration of available nutrients.

Explanation: It is important to know that the equation listed above is a summary equation. The process of cellular respiration involves many different steps (reactions) to break down glucose using oxygen to produce carbon dioxide, water and energy in the form of ATP.

During photosynthesis, the plant needs carbon dioxide and water– both of which are released into the air during respiration. And during respiration, the plant needs oxygen and glucose, which are both produced through photosynthesis!

Fermentation is a metabolic process that consumes sugar in the absence of oxygen. The products are organic acids, gases, or alcohol. It occurs in yeast and bacteria, and also in oxygen-starved muscle cells, as in the case of lactic acid fermentation. The science of fermentation is known as zymology.

Cellular respiration releases carbon dioxide, which is used in photosynthesis. Photosynthesis in turn releases oxygen used in respiration. Animals and other heterotrophs depend on green organisms for organic food, energy, and oxygen. In the carbon cycle, organisms exchange carbon dioxide with the atmosphere.

The Function of ATP. The ATP is used for many cell functions including transport work moving substances across cell membranes. It is also used for mechanical work, supplying the energy needed for muscle contraction.

Three factors can limit the speed of photosynthesis – light intensity, carbon dioxide concentration and temperature. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis.

A respirometer is a device used to measure the rate of respiration of a living organism by measuring its rate of exchange of oxygen and/or carbon dioxide. The oxygen uptake is detected by manometry.
