Why are lactate and ethanol formed under anaerobic conditions?
Short Answer: To regenerate NAD+ for the continued function of glycolysis.Detailed Answer: As NADH is formed in glycolysis (2 NADH per glucose), NAD+ must be regenerated to allow continued glycolytic flux (and consequent production of ATP). In the presence of adequate oxygen (i.e. under aerobic conditions), this regeneration takes place predominantly in the mitochondria. Under anaerobic conditions, however, the only way to regenerate NAD+ is through lactate fermentation (e.g. mammals) or ethanol fermentation (e.g. yeast).
Athletes sometimes complain of oxygen debt a condition that results when insufficient oxygen is available to completely break down pyruvic acid As a result the pyruvic acid is converted to?
lactic acid through anaerobic metabolism. This process can produce a buildup of lactic acid in muscles, leading to muscle fatigue and discomfort. Adequate oxygen levels are needed to break down pyruvic acid efficiently through aerobic metabolism without accumulating lactic acid.
In order to move molecules in your kidney what does your body need?
Your body needs energy in the form of ATP to transport molecules in your kidneys. This energy is used by transport proteins to pump molecules across cell membranes and maintain the proper balance of ions and fluids in the body. Additionally, adequate hydration and blood flow are necessary to support the movement of molecules in the kidneys.
Do peach trees bear fruit every year?
Generally yes, but only if environmental conditions are adequate (water, chill hours, adequate drainage and soil nutrients). Its not uncommon to have a peach tree "skip a year" due to draught, disease, insects or other extreme conditions.
Why do warmer and wetter biomes have better net primary productivity?
Warmer and wetter biomes have better net primary productivity because warm temperatures increase the rate of photosynthesis in plants, allowing them to grow faster and produce more biomass. Additionally, higher moisture levels ensure that plants have access to an adequate water supply, which is essential for their growth and metabolism. These conditions help to support a greater abundance and diversity of plant species, leading to higher overall productivity in these biomes.

How do you differentiate between aerobic and anaerobic cells?
Strictly speaking, the terms "aerobic" and "anaerobic" refer to the presence and absence of oxygen, respectively. Most of our cells prefer to get their energy by using oxygen to fuel metabolism. During exercise with adequate fuel and oxygen (i.e., aerobic), muscle cells can contract repeatedly without fatigue. During anaerobic or non-oxygen conditions (i.e., higher intensity exercise), muscle cells must rely on other reactions that do not require oxygen to fuel muscle contraction. This anaerobic metabolism in the cells produces waste molecules that can impair muscle contractions. We call this deterioration in performance fatigue.Fatigue causes you to experience added discomfort and weakening muscles. Eventually you will need to slow down and lower your exercise intensity. Slowing down allows the muscles to once again rely solely on aerobic metabolism and support the removal or chemical conversion of waste molecules.The problem with the terms "aerobic" and "anaerobic" when applied to exercise is that we actually never switch from total aerobic to total anaerobic metabolic conditions. In reality, the more intensely we exercise, the greater the need for anaerobic energy production. Consequently, it is best to view the terms aerobic and anaerobic as transitions in metabolism, where the proportion between aerobic and anaerobic metabolism changes depending on exercise intensity.For example, while at rest, we rely on aerobic metabolism to fuel almost all our body's needs for energy. As we start to exercise, such as progressing from sitting to a slow walk, the increased energy needs of muscle contraction require that we increase our breathing and oxygen intake. So long as we increase our exercise intensity slowly, we can maintain our muscles' dependence on aerobic metabolism, and we don't experience symptoms of fatigue.However, as exercise intensity increases, the need for energy release eventually exceeds that which can be supplied by aerobic metabolism. Our muscles simply need more reactions to support the energy demand. Therefore, anaerobic contribution to metabolism increases. When this happens, we refer to this change in metabolism as a metabolic threshold. This metabolic threshold represents the exercise intensity where we start to produce those waste products of anaerobic metabolism that can eventually lead to fatigue. You see this all the time when watching endurance Olympic events, such as a long distance running race. The athletes run at a pace that hovers around their metabolic threshold, and they can only afford to run faster than this pace near the end of the race. If they increase their pace too early in the race, then they fatigue too early and need to slow down to below their metabolic threshold to recover from the fatigue inducing waste products. This would result in poor performance.So how do these terms relate to you? Well, it depends on your circumstance and goals. Most of us are non-competitive or non-elite active individuals, who just want to exercise to gain health benefits, feel good and possibly lose weight. Aerobic exercise conditions enable you to exercise for long periods of time, potentially benefiting from the sustained energy expenditure (i.e., calories burned). Aerobic exercise tends to be less stressful to muscles, joints, and your heart, which may be important for individuals with arthritis, heart disease, or high blood pressure. However, to more rapidly improve your exercise capacities, tolerance, and performance, some anaerobic exercise training is a necessity. Therefore, performing anaerobic exercise is typically more important for competitive athletes.When starting a training program, most trainers like to have their clients/athletes start with lower intensity exercise (i.e., aerobic exercise). However, a high reliance on anaerobic metabolism is unavoidable for some types of exercise or activities. For instance, lifting weights is anaerobic. That is why muscles fatigue so rapidly with this type of training. Other types of activities, such as walking up stairs, can also be anaerobic - especially if you are unfit or climb too fast.Fortunately, we do not need sophisticated equipment to detect when we transition from aerobic to anaerobic exercise. As we approach and pass our metabolic threshold intensity, we start to breath harder, we are forced to really concentration on the exercise/activity, and exercise simply becomes uncomfortable. However, if you simply love gadgets, you can use a heart rate monitor to record the heart rate at which you sense these symptoms of developing over-exertion. You then know that heart rates below this value occur when you're in your aerobic zone, and heart rates above this value reflect an increasing anaerobic contribution to your exercise bout.

Does light affect a mealworms speed of growth?
Yes, light can affect a mealworm's growth rate. Mealworms are more active and tend to grow faster in light conditions compared to in darkness. Providing adequate light can help stimulate their metabolism, leading to increased growth and development.
Which muscle cells break down glucose to generate ATP under oxygen deficient conditions they will form?
Muscle cells that break down glucose to generate ATP under oxygen deficient conditions will form lactic acid. This process is known as anaerobic glycolysis, where glucose is converted into lactic acid in the absence of adequate oxygen for cellular respiration.
What does lactic acid have to do with respiration?
Lactic acid is produced by anaerobic respiration (when there is an absence or insufficiency of oxygen intake). If there is adequate oxygen (provided by respiration) and metabolic fuel, lactic acid is not produced.
What blocks aerobic metabolism by interfering with cell use of oxygen?
Carbon monoxide is a gas that can block aerobic metabolism by binding to hemoglobin in red blood cells more strongly than oxygen, preventing adequate oxygen delivery to tissues. This interference can disrupt the cell's ability to use oxygen for energy production through aerobic metabolism.
