What Is The Approximate Value For The Thermic Effect Of A 2500 Calorie Diet?
An individual’s thermic effect of food is defined as the energy expenditure above what is required to process and store consumed foods. The amount varies by nutrient composition, so to calculate an approximation, you need to know the average caloric value of a 2,500 calorie diet.
According to Stanford Medical School, this number can range from 2,000-3,000 depending on your daily caloric intake level. For every 1,000 calories over 2,500 per day that you consume in addition to your basal metabolic rate (which accounts for around half of your total daily energy expenditure), you would likely spend an extra 50 calories per day on the processing and storing of this food.
This means that if you had a 3,500 calorie daily diet, you would likely spend an additional 150 calories per day processing this food. The amount over 2,500 is typically minimal.
For example, if you had a 3,000 calorie diet that consisted of 20% protein (in the form of lean meat), 30% fat, and 50% carbohydrates, you would only burn an extra 25-30 calories per day compared to someone with a 2,000 calorie diet containing 10% protein (the same as your intake) and 90% carbohydrates.
Which of the following is a feature of the lipoprotein lipase enzyme:
A) It is synthesized mainly in the liver.
B) Its activity can be regulated by cAMP-mediated phosphorylation.
C) The enzyme binds to the endothelial cell surface through glycoprotein Ib/IX/V complex protein gpIbα.
D) Each monomeric subunit contains an amino acid sequence that is homologous to that of the C-terminal domain of plasminogen
E) It hydrolyses triacylglycerol substrates with high efficiency within cells and thus provides substrate availability for oxidation or storage as lipids in adipose tissue or other cells. (this multiple choice question has been scrambled) It is synthesized mainly in the liver. Reviews of Biochemistry – Lipoprotein lipase
Correct Answer: A
Explanation
A) It is synthesized mainly in the liver. – Review of Biochemistry – Lipoprotein lipase
B) Its activity can be regulated by cAMP-mediated phosphorylation.
C) The enzyme binds to the endothelial cell surface through glycoprotein Ib/IX/V complex protein gpIbα.
D) Each monomeric subunit contains an amino acid sequence homologous to that of the C-terminal domain of plasminogen. This incorrect option has been removed from the article body due to a lack of evidence supporting it being a feature of the lipoprotein lipase enzyme.
E) It hydrolyses triacylglycerol substrates with high efficiency within cells and thus provides substrate availability for oxidation or storage as lipids in adipose tissue or other cells. This incorrect option has been removed from the article body due to a lack of evidence supporting it being a feature of the lipoprotein lipase enzyme.

Correct Answer: A
Explanation
A) Elevated levels of fibrinogen – Review of Biochemistry – Homocysteine and Coronary Artery Disease This incorrect option has been removed from the article body due to lack of evidence supporting it being a risk factor for coronary heart disease.
B) Low blood pressure.
C) Obesity.
D) Smoking.
E) Elevated levels of homocysteine in the plasma. This incorrect option has been removed from the article body due to lack of evidence supporting it being a risk factor for coronary heart disease. which of the following is true concerning rheumatoid arthritis:-
A) It is more prevalent in women than men (ratio typically between 2:1 and 3:1).
B) Rheumatoid factor is clinically detectable in most patients with active disease but not in those with inactive disease or RA-NOS.
C) The redness sometimes associated with early morning stiffness typically does not involve the fingers (so-called dactylitis).
D) The identification of anti-cyclic citrullinated peptide antibodies (anti-CCP antibodies) is helpful for the diagnosis of rheumatoid arthritis.
E) The most common pattern of extra-articular involvement in RA includes psoriasis and uveitis.
