Explanation:
Muscle contraction requires lots of energy. Describe the three ways muscle cells generate ATP. Be sure to include which pathway will supply energy the quickest and which will supply energy over the longest period of time.
Answer: Direct Phosphorylation( quickest), Anaerobic Respiration, Aerobic Respiration (longer period of time).
Explanation: The energy which can be used by our body for muscle contractions can be generated by muscles cells in three different ways. These includes:
--> Direct Phosphorylation
--> Anaerobic Respiration and
--> Aerobic Respiration.
DIRECT PHOSPHORYLATION: As ATP is used up, it's re-stocked by the small reserve of energy stored as creatine phosphate. Creatine phosphate very rapidly donates its high-energy phosphate to ADP the moment ADP forms, converting it back to ATP. This extra source of ATP is easily mobilized and is very effective as long as it last. It's limited though because the store of creatine phosphate is small. (Normally the supply of creatine phosphate is re-stocked by oxidative metabolism via the ATP produced by the citric acid cycle, but during intense exercise there is not enough time to do this so the stock is burned in 20-25 sec making it the QUICKEST way to supply energy)
ANAEROBIC RESPIRATION: When oxygen levels in the cells are low, glucose molecules undergoes glycolysis to produce 2 molecules of pyruvic acid( ATP). The pyruvic acid is converted anaerobically to lactic acid. The build up of lactic acid causes the pain and cramps of overexercised muscles. It is a fast but an inefficient way of producing ATP for energy use.
AEROBIC RESPIRATION: This occurs only if the oxygen supply is adequate and is the process by which energy is released during prolonged exercise. It utilizes glucose and glycogen. During the glycolysis process, a glucose molecule is converted to 2 molecules of ATP in the cytoplasm of cell. In the presence of sufficient oxygen, the pyruvic acid enters the citric acid cycle and oxidative phosphorylation giving rise to the by products of 36 ATP, carbon dioxide and water. Aerobic respiration is SLOW (takes the longest period) but efficient process.
why is it important that the dna polymerase be heat resistant
Answer: Heat stable DNA Polymerase; heat stability is very important because PCR reaction is performed at various temperatures. This heat stable DNA polymerase is obtained from a thermophilic bacteria Thermus aquaticus, the inhabitant of hot springs. Hence, this DNA polymerase is termed as Taq DNA Polymerase.
DNA polymerase I function to fill DNA gaps that arise during DNA replication, repair, and recombination.
DNA polymerase:t's DNA polymerase is very heat stable and is highly reactive at 70*C. This heat stability makes Taq polymerase ideal for PCR, as high temperature is used repeatedly in PCR to denature the template DNA, or separate its strands. Polymerase activity is strongly influenced by temperature.
Taq DNA polymerase is the most common enzyme used for PCR amplification.

Which formula is an ionic compound?
NaF
N2
NO2
CO2
Answer:
NaF I took the test, hope this helps. :)
Explanation:
NaF is an ionic compound. Ionic compounds have ionic bonds between the molecules.
What is ionic compound?Because each atom contains a particular combination of protons, neutrons, and electrons, each atom is singular. An atom typically has the same number of protons and electrons.
And while the number of protons in an atom can never vary because doing so would result in the presence of an entirely other element, the number of electrons can occasionally shift.
Adding or taking away electrons from an atom alters the charge of the atom since electrons have a net negative charge by themselves. This is due to an imbalance between the number of protons, which have a positive charge, and the number of electrons.
Therefore, NaF is an ionic compound. Ionic compounds have ionic bonds between the molecules.

HURRY PLEASE. List the four types of organic compounds found in all living things and explain why they are important.
Answer:
Explanation:
Four organic molecules make up all of the life on Earth. Organic molecules contain carbon and hydrogen chemically linked to one another in long chains, with carbon as the backbone and hydrogen atoms attached to the carbon atoms. These atoms' ability to attach to one another allows for the creation of innumerable compounds conducive to life. All organisms need four types of organic molecules: nucleic acids, proteins, carbohydrates and lipids; life cannot exist if any of these molecules are missing.
Nucleic Acids
The nucleic acids are DNA and RNA, or deoxyribonucleic acid and ribonucleic acid, respectively. They make the proteins that are present in almost every structure and perform almost every function in your body. DNA has a twisted ladder-like form, while RNA has many different shapes, depending on its function. DNA typically remains within the center, or nucleus, of a cell; RNA can travel throughout the cell to where it is needed. The backbones of both substances consist of alternating molecules of phosphate and sugar. Nucleotide bases make up the "rungs" attached to the backbone. Of the two types of nucleic acids, DNA is more stable, making it less likely to be broken down than RNA. Your genes are made up of DNA, and each gene provides the code for making a specific protein. RNA helps DNA to make these proteins.
Proteins
Proteins are probably the most versatile of all the organic molecules, making up many structures and executing various functions within organisms. Building blocks called amino acids make up proteins. About 20 different amino acids combine to form all of the various types of proteins on Earth. These amino acids all have almost the exact same composition; the only difference is the R group, which differs in each of the amino acids and gives them their uniqueness. When a protein is made, the protein comes together one amino acid at a time within the ribosome -- a structure that houses protein synthesis. Proteins have four levels of structure: The primary structure is the bonding of amino acids to one another; the secondary structure refers to the folds in certain areas within the protein; the tertiary structure is the ultimate three-dimensional look of the protein; and the quaternary structure consists of smaller protein subunits chemically bonded together to form a larger protein.
Carbohydrates
Carbohydrates comprise the largest number of organic molecules in organisms. Basically, carbohydrates are sugars; their origin can be traced to photosynthesis, the process by which organisms such as plants use sunlight to transform carbon dioxide and water into food. The simplest sugar is glucose, a molecule used to provide fuel for many types of organisms, including humans. The sugars found in foods include: fructose in fruits, galactose in milk, maltose in vegetables and sucrose in table sugar. The starch found in whole grains and vegetables is a complex carbohydrate made of chains of simpler glucose molecules. Your body contains an enzyme called amylase, which breaks down carbohydrates in the food you eat into glucose, which your cells can use as energy.
Lipids
Lipids, perhaps better known as fats, come in different forms in your body and contain the most energy of all the organic compounds. When your body burns lipids for fuel, you get more energy than if you burned the other organic molecules. In your body, fats perform many functions, taking the form of phospholipids and cholesterol, both important components of cell membranes; waxes that provide plants and animals with a protective layer; hormones that signal different functions in your body; vitamins that aid in different cell functions; and steroids, which are important in a number of physiological processes. Fats from animals tend to be more viscous than fats from plants.
