Summarize the steps of glycolysis using the key terms ATP, ADP, NAD+, NADH, glucose, and pyruvate.
Explanation:
LOOK AT THE FLOW CHART
IT MIGHT HELP U OUT
In this question we summarize the steps of glycolysis which is a process that occurs through a series of 10 reactions divided into two steps using the key terms ATP, ADP, NAD+, NADH, glucose and pyruvate.
Steps of glycolysis1st stage
This step, also known as the preparatory phase or investment phase, consists of five reactions:
1. Phosphorylation of the glucose molecule occurs, in which it receives phosphate from the ATP molecule, forming glucose 6-phosphate;
2. The glucose 6-phosphate molecule undergoes a rearrangement and forms fructose 6-phosphate;
3. Another ATP molecule supplies phosphate to the fructose 6-phosphate molecule, giving rise to fructose 1,6-diphosphate;
4. The fructose 1, 6-diphosphate molecule undergoes a rearrangement, with the opening of its benzene ring, giving rise to two molecules with three carbons each: glyceraldehyde 3-phosphate and dihydroaxethone phosphate;
5. The dihydroaxethone molecule undergoes a rearrangement giving rise to another glyceraldehyde 3-phosphate molecule.
It can be seen that at the end of this first phase, there was only energy expenditure, with the conversion of two ATP molecules into ADP.
→ 2nd stage
This stage, also known as the profit or energy compensation stage, involves energy gain and also consists of five stages, described below:
6. Two molecules of NAD+ (nicotinamide dinucleotide and adenine) are reduced to two molecules of NADH with electrons from the oxidation of glyceraldehyde 3-phosphate to 1,3-diphosphoglycerate;
7. Each molecule of 1,3 – diphosphoglycerate yields a phosphate to one molecule of ADP, thus giving rise to two molecules of ATP and two molecules of 3 – phosphoglycerate;
8. A rearrangement of 3 – phosphoglycerate molecules occurs, forming 2 – phosphoglycerate;
9. The 2 – phosphoglycerate molecules lose a H2O molecule, giving rise to phosphoenolpyruvate;
10. Phosphoenolpyruvate molecules provide a phosphate to an ADP molecule, yielding two ATP and two pyruvate molecules.
With this information, we summarize the steps of glycolysis which is a process that occurs through a series of 10 reactions divided into two steps using the key terms ATP, ADP, NAD+, NADH, glucose and pyruvate.

A person starts to eat a hamburger. As she takes a bite and chews, an enzyme called salivary lipase helps to begin the process of fat digestion. Which of these is the BEST description of the role of enzymes in digestion?
Answer:
Role of enzymes in the human body
Explanation:
The chemical reactions that keep us alive - our metabolism - rely on the work that digestive enzymes do. They help to accelerate (catalyze) chemical reactions in the human body.
In some cases, they can cause a chemical reaction millions of times faster than they would without them.
Important functions of enzymes:
Digestive enzymes help the body break down larger complex molecules into smaller ones such as glucose, so it uses them as fuel.
Every cell in our body contains DNA. Each time the cell divides, this DNA must be copied. The process is called DNA replication . Enzymes help in this process by developing the DNA helix and copying the information.
Liver enzymes break down toxins in the body.
Enzymes are especially needed for respiration, digestion, muscle and nerve function, among other important roles.
Answer:
C. Enzymes are proteins that speed up the process of chemcially breaking down food molcules.
Explanation:
A farmer has grown strawberries successfully for years in field A. He recently expanded the crop into previously unused land in fields B and
C. The yield from field B is comparable to A, but the yield from field C is inexplicably low. As a microbiome expert, what might you predict
about the soil of fields A, B, and C?
Given what we know, we can confirm that the soil in field C most likely lacks the presence of microbes that help plants grow or has a higher presence of microbes that are harmful to plant growth.
What does it mean for a microbe to promote plant growth?This would mean that the microbe in question has a symbiotic relationship with plants. Meaning that it promotes plant growth in exchange for nutrients from the plant, and both organisms will benefit, similar to microbes such as AM fungi.
Therefore, we can confirm that the soil in field C is likely to lack plant symbiotic microbes that are most likely found in fields A and B.

What is the main difference between natural selection and
selective breeding? in selective breeding
humans allow nature to control the reproduction of species
humans choose plants or animals for reproduction
the strongest will survive and have more offspring
the organisms with the most genetic variation will reproduce
Answer:
humans choose plants or animals for reproduction
Explanation:
This can be seen in the farming industry with livestock and crops alike. Crops are usually chosen for a genetic resilience (like to arid, dry areas) and are reproduced with intervention from humans. This doesn't happen in the wild, therefore it is natural vs the unnatural and purposeful human intervention.

11. Make a checklist for
a client to use to
determine normal and
abnormal behaviors of a
pet. Include & label
behaviors that require an
owner to seek veterinary
attention.
Veterinarians have a great opportunity to save pets’
lives by recognizing that behavioral medicine is as
important as any other field of veterinary medicine,
and can routinely be incorporated into each veterinary
visit. Because most veterinarians never received education in veterinary school about feline behavior, and do
not have the time and resources to study all the latest
research and develop behavior protocols, the panelists
have worked to develop a concise, updated and “user
friendly” document that can be easily implemented.
The guidelines include the following information:
• Emphasis is on prevention, from pre-adoption or the
first veterinary visit, through senior life. Preventing
behavior problems should be an important part of total
wellness care. A list of behavior questions intended for
inclusion in the medical history questions used at each
appointment is provided to aid in early detection and
intervention of behavior problems.
• An outline is provided for guidance regarding how to
create realistic expectations about living with a cat. This
will encourage cat owners to provide positive outlets to
allow normal behavior, but in ways that clients will consider acceptable.
• Several of the appendices can be used for both prevention and treatment and can be made into client
handouts; these will delegate client education to the
veterinary support team and be used to facilitate the
veterinarian’s role in client education.
• A developmental table specifying home and veterinary
care needed at different stages of life is included. This
can serve as an excellent poster or client information
handout to help clients understand their responsibilities for home and veterinary care.
• Detailed information on behavior and environmental
enrichment is included to help prevent many of the
most common behavior problems.
• Suggestions regarding prevention and treatment of
obesity, the most common consequence of domestication of cats, are provided.
• To help veterinarians better handle routine behavior
concerns (eg, inappropriate elimination) a rational first
approach to the problems seen day-to-day is included.
• Behavior counseling and treatment, including behavior
modification and environmental enrichment, are discussed in detail. For cats needing medical treatment,
important drug information including dosing and
tapering of medication is provided. Information on
where to refer if needed is also provided.
• Information is provided that will promote comprehensive, state-of-the-art, holistic care that incorporates
both the physical and psychological well-being of our
feline patients.
• These guidelines will help veterinarians raise client
awareness that they should turn to the veterinary profession for advice regarding behavior, just as they do
with any medical concerns.
