Aerobic respiration is the kind that occurs when there is a non limiting supply of oxygen; anaerobic respiration occurs when there is a limiting supply of oxygen...
Yeast cells can ferment, so they can grow in the absence of oxygen. This is important in the process of alcoholic fermentation to make wine and beer.
Answer:
fermentation will take place to produce low levels of ATP..lmk if i helped ya byeeeeeeeeee

Answer:
humerus.
Explanation:
Here are some key points about the humerus:
1. Length: The humerus is the longest bone in the upper limb, measuring about one-third of the length of the entire upper limb.
2. Structure: It is a long bone that consists of a shaft and two ends. The shaft is cylindrical in shape and has a slightly curved appearance. The upper end of the humerus forms part of the shoulder joint, while the lower end articulates with the bones of the forearm at the elbow joint.
3. Articulations: The humerus forms two important joints in the upper limb. The upper end articulates with the scapula (shoulder blade) to form the shoulder joint, also known as the glenohumeral joint. The lower end articulates with the radius and ulna bones of the forearm to form the elbow joint.
4. Function: The humerus plays a crucial role in various movements of the upper limb. It allows for flexion, extension, abduction, adduction, and rotation of the arm. These movements are essential for activities like lifting, pushing, pulling, and throwing.
5. Muscles attachment: The humerus provides attachment points for several muscles involved in upper limb movements. These include the deltoid, biceps brachii, triceps brachii, and many others.
In summary, the humerus is the longest and largest bone of the upper limb. It supports the arm and enables a wide range of movements in the shoulder and elbow joints.
Answer:
The total energy production of a mitochondrion is enhanced by its large internal surface area.
Explanation:
All cellular activity requires energy, it is through mitochondria that this energy necessary for cell activity will be generated. Mitochondria has a large internal surface area, all of which strongly influences the energy production of this organelle.
To get energy, the cell necessarily needs glucose. Mitochondria have the function of breaking down glucose by introducing oxygen into carbon, what remains is carbon dioxide, which will come out through exhalation. This process performed by this important cellular organelle is known as cellular respiration. In order for cells to perform their functions normally, they depend on various chemical reactions that occur within the mitochondria.
Despite its great importance, mitochondria is a fairly small cell organelle. There are cells that have a large number of mitochondria, however, the amount of this organelle will depend on the function of each one. The more the cell needs energy to perform its vital functions, the more mitochondria it will produce.
Chief cells produce pepsinogen, while parietal cells secrete hydrochloric acid (HCl) in the stomach for protein digestion.
Chief cells, located in the gastric glands of the stomach, release pepsinogen, an inactive precursor enzyme. Pepsinogen is converted to its active form, pepsin, by the acidic environment in the stomach. Pepsin plays a vital role in breaking down proteins during digestion. Parietal cells, also present in the gastric glands, are responsible for secreting hydrochloric acid (HCl).
This strong acid serves several crucial functions in the stomach. It activates pepsinogen to pepsin, facilitating protein digestion. Additionally, HCl creates the highly acidic environment necessary for pepsin's action and further protein breakdown. Moreover, the acidic conditions in the stomach help sterilize the contents, neutralize harmful microorganisms, and enable the absorption of certain nutrients.
