Lactic acid fermentation can be modeled by which equation?

1 answer:

4 0

Lactic acid fermentation can be modeled by the following equation: Pyruvic acid + NADH → Lactic acid + NAD+

LACTIC ACID FERMENTATION:

Fermentation is a process undergone by some anaerobic organisms. Ideally, the process of cellular respiration proceeds as follows in the presence of oxygen: Glycolysis- Kreb cycle - ETC.

However, in the absence of oxygen (anaerobic condition), the product of glycolysis which is pyruvic acid combines with an electron carrier (NADH) to give rise to lactic acid and NAD+.

This means that pyruvic acid is reduced while NADH is oxidized as modelled in the following equation:

Pyruvic acid + NADH → Lactic acid + NAD+

A woman at 26 weeks of gestation is being assessed to determine whether she is experiencing preterm labor. Which finding indicat

My name is Ann [436]

Answer:

A. The cervix is effacing and dilated to 2 cm.

Explanation:

PRETERM LABOUR:

DEFINITION:

Preterm labor is defined as labor or delivery that occurs before 37 weeks of gestation.

DIAGNOSIS

A pregnant patient is said to be undergoing preterm labor if:

Regular Uterine contractions ( at least 1 in 10 minutes).
Dilation of cervix up to 2 cm or greater and effacement of cervix up to 80%
Patient experiences pelvic pressure, backache, vaginal discharge or bleeding
Cervix is shortened up to less than 2.5 cm with funneling of internal os when examined by Transvaginal Ultrasound

Fetal Fibronectin is a glycoprotein that if found in vaginal secretion between 24 and 34 weeks of gestation is an excellent predictor of preterm labor and indicates that the patient is at high risk of undergoing of preterm labor.

Similarly, increased levels of maternal salivary estriol is a predictor of preterm labor.

Coming back to the answer choices,

A. The cervix is effacing and dilated to 2 cm.

This is the correct answer choice as effacement of cervix and dilation of cervix upto 2cm or greater is a diagnostic feature of preterm labor.

B. Irregular, mild uterine contractions are occurring every 12 to 15 minutes.

Regular uterine contractions at least 1 in 10 minutes is diagnostic of preterm labor. Therefore this is the incorrect answer choice. However, Uterine contractions equal to or greater than 4 per hour is a good predictor that patient will undergo preterm labor.

C. Fetal fibronectin is present in vaginal secretions.

Presence of fetal fibronectin in vaginal secretions is an excellent predictor of preterm labor. Therefore, this answer choice is inappropriate.

D. Estriol is not found in maternal saliva.

Elevated maternal salivary estriol is a predictor of preterm delivery. Therefore, this answer choice is also incorrect.

Which high grade, foliated metamorphic rock has visible crystals?

Fudgin [204]

Answer:

Gneiss

Explanation:

Gneiss forms at the highest pressures and temperatures and has crystals large enough to see with the unaided eye. Gneiss features minerals that have separated into bands of different colors. The bands of colors are what define foliation within gneiss.

Each of two parents has the genotype green divided by brown, which consists of the pair of alleles that determine eye color, a

Liula [17]

Answer:

A)BB-Bg-Bg-GG

B)The probability is 25%

C)The probability is 75%

Explanation:

In order to solve this you just have to create a punnet square, where the parents are shown to both have brown and green coloured eyes genes, so it would be like this:

Mother: Brown Green

Father↓

Brown Brown-Brown Brown-Green

Green Brown-Green Green-Green

As the instructions say that if any kid had one green allele that would be the dominant, only the Brown-Brown will show the fenotype, so there´s 1/4 chance to happen, or 25%, the other probability of having green eyes is 3/4 or 75%
