Usually during exercise, unlike during rest times the muscle cells need to respire more. So they need more oxygen and glucose for energy and the carbon-dioxide produced as waste must be removed quickly. So when person gets tired or breathes heavily during intensive workouts means they are in need of more oxygen. So the cells starts performing anaerobic(lactic acid ) respiration even though it releases less energy.
The answer is C) Living organisms use matter and energy for their life processes.
Hope this helps :)
Answer:
A. 60 grams protein
B. 74 grams of protein
Explanation:
The amount of protein needed depends on weight and lifestyle. The daily minimum recommended by the National Institutes of Health is 0.36 grams per pound for a sedentary person. But the daily optimal intake for this same sedentary person is 0,8 grams of protein per kg of body weight. On the other hand hand, adults with a more active lifestyle need more protein in their body, the intake should be between 1,2 and 2,0 grams of protein per kg. For example, endurance runners need up to 1,4 and strength training athletes need up to 1.8 g of protein per kg.
The first step for calculating protein requirements is calculate the weight in kilograms, so we need to divide the weight in pounds by 2,2.
154lb/2,2= 70 kilograms
Then we have to multiply the weight in kg, times the number of protein needed per day, 0,8 for a sedentary healthy adult.
70kg x 0,8= 56 grams
Part A:
165-pound (lb) male who is healthy but sedentary
165 lb/2.2 = 75 kg
75 kg x 0,8 = 60 grams protein per day
Part B. Sarah is moderately active so we need to use a number between 1,2 and 2, since shes active but not very active we can use the 1,2.
136-lb/2,2= 62 kg
62 kg x 1,2 = 74 grams of protein
