4 0

Answer:

(Wow! Weird how this pooped up, I just finished this biology lesson.)

Sex chromosomes are the gene that decides on our gender. The males have X and Y sex chromosomes (XY). Females have only two  X sex chromosomes (XX).

More info: Because males have both X and Y sex chromosomes, their genes decide the offspring's gender.

PFK can be allosterically inhibited by ATP at high concentrations. Which of the following is the benefit of regulating glycolysi
melamori03 [73]

Answer:

The principle benefit of regulating glycolysis by the concentration of ATP is to signals the cell to stop glycolysis as sufficient amount of ATP is already present in the biological system.

Explanation:

Phosphofructokinase 1 is allosterically inhibited by ATP.Glycolysis is a catabolic as well as exergonic process which deals with the oxidation of glucose to form pyruvate along with ATP molecules.

            When ATP is present at high concentration within our body at that time there is no need to synthesize additional ATP because ATP is already present in sufficient amount.

       To maintain its own homeostasis ATP allosterically inhibit the catalytic activity of phosphofructokinase. As a result glycolysis is inhibited and the glucose molecule can be utilized in other metabolic pathways.

1. Discuss at least two attributes of a study that you would look for to determine whether or not it is rigorous.
noname [10]

Some of the aspects that help you determine whether a study is rigorous are questions and hypotheses that can be answered, adequated method use, and bibliography.

Rigorous is a term that refers to a quality that focuses on accuracy and precision to comply with norms, precepts, and pre-established rules. This term is widely used in science to refer to the precision of a study or investigation.

Therefore, when it is established that a study is rigorous, its attributes must be taken into account, such as:

- Questions and hypotheses that can be answered: This aspect refers to the investigator having the ability to limit his study so that it is appropriate to do so and does not include too much information that makes his study "impossible".

- Adequated methods use: This refers to using the appropriate methods to reach feasible conclusions, for example, methods of observation, deduction, induction, among others.

- Bibliography: This refers to the research or study being supported by reliable sources so that it is as accurate as the information it provides.

Why is salivary amylase active for only an hour or so, whereas lingual lipase isn't active until reaching the stomach
leva [86]

Salivary amylase will be active for only an hour or so because the optimum pH for activity of amylase is about 6.7–7.0 which is available in the mouth but the pH of the stomach is acidic around 1-2 due to which the amylase enzyme becomes inactive in short-time.

The lingual lipase enzyme is present in the saliva but isn't active until reaching the stomach because this enzyme is acid stable and works efficiently in the stomach, not in the mouth.

Amylase enzyme is secreted in the mouth and is responsible for the breakdown of starch in food into sugars and it starts acting as soon as we put food in the mouth whereas Lingual lipase enzyme is secreted along with saliva but it is not active in the mouth rather its activity starts in the stomach which is responsible for the degradation of triacylglycerol molecules.
