Cellular Respiration. Glycolysis is the first step of cellular respiration. It turns glucose into pyruvate, NADH, and ATP. The pyruvate is then used in pyruvate oxidation to create Acetyl CoA, NADH, and CO2. Acetyl CoA is then fed into the citric acid cycle (TCA cycle) where NADH, FADH2, ATP, and CO2 are produced. All of the NADH and FADH2 that were produced thus far are then fed into the ETC (orange). The ETC uses electrons from NADH and FADH2 to pump protons across the inner mitochondrial membrane (this is the oxidation piece). ATP synthase (purple) uses the protons to phosphorylate ADP, making ATP (this is the phosphorylation piece). https://images.squarespace-cdn.com/content/v1/63bdf003af127a1e397dafec/b619ac8f-a0e5-436f-bc02-877ec99c3f0e/052024_MM_CellularRespiration6Panel.png Blog - The mitochondria: function, implications of dysfunction, and actions you can take to promote mitochondrial health - Figure 3. Cellular respiration with breakdown of OXPHOS. Orange numbered bubbles indicate cellular respiration steps, with OXPHOS being broken into two parts, oxidation and phosphorylation. Frames: A) Zoomed in view of where cellular respiration takes place and the mitochondrial components involved. B) The first two steps of cellular respiration: (1) glycolysis, which takes place in the cytosol, and produces pyruvate to be used in (2) pyruvate oxidation, which produces acetyl CoA– an input for (3) TCA cycle. C) TCA cycle produces NADH and FADH2. D) The NADH and FADH2 are used by the ETC to move protons into the intramembranous space. This is (4.1), the oxidation piece of oxidative phosphorylation. E) A proton gradient is formed with the higher concentration of protons in the intramembranous space, and the lower concentration in the matrix. F) ATP synthase takes advantage of this gradient and uses the intramembranous protons to phosphorylate ADP, making (30-32) ATP. This is (4.2), the phosphorylation piece of oxidative phosphorylation. https://www.calorify.com/blog/implications-of-precision-metabolic-testing monthly 0.5 2024-11-13 https://images.squarespace-cdn.com/content/v1/63bdf003af127a1e397dafec/1a69b1b1-a15b-4db4-86fe-50b2d98d1509/Screenshot+2024-03-28+at+10.04.13+AM.png Blog - Implications of Precision Metabolic Testing Using Doubly Labeled Water - Figure 1.

DLW steps in to reveal their secret. A study found that these cuddly creatures have an incredibly low TEE, only 37.7% of the predicted value. Pandas achieve this evolutionary feat through a combination of reduced organ sizes, low physical activity, and even a unique genetic mutation. DLW helped unveil some of the metabolic mysteries behind these gentle giants. https://images.squarespace-cdn.com/content/v1/63bdf003af127a1e397dafec/1704929445466-1T0L9KOOCXYHLF4SPIPF/image-asset.jpeg Blog - Beyond Calories: DLW's Exciting Adventures - Orangutans: Surviving Fame and Famine Orangutans were measured using DLW and researchers discovered that they used less energy, relative to body mass, than nearly any mammal ever measured, including sedentary humans!

DLW enters the world of African elephants in captivity, highlighting changes in body mass, fat percentage, and fat-free mass in response to diet modifications. DLW not only provides insights into the physiology of elephants but also emphasizes their water dependence, crucial for their well-being. Fun fact: their water throughput is over 350 liters per day - that’s equivalent to an entire bathtub every day! https://images.squarespace-cdn.com/content/v1/63bdf003af127a1e397dafec/1704929612584-IFVZ5GY0TPHZ5LR8R0GQ/image-asset.jpeg Blog - Beyond Calories: DLW's Exciting Adventures - Humans and Evolution: Our Energy Odyssey DLW steps into the realm of human evolution, showing how our metabolism evolved to support our species’ big brains, slow childhood growth, and long lives. The answer? We burn more calories! When compared to other primates, we burn 400-820 calories more each day, even when accounting for our size and physical activity level. That increased expenditure, as well as higher fat stores, helps to show how we as humans provide energy for larger brains and faster reproduction without sacrificing maintenance and longevity! https://images.squarespace-cdn.com/content/v1/63bdf003af127a1e397dafec/1704929670960-V7RS3PB8MAOGGESVDZAI/image-asset.jpeg Blog - Beyond Calories: DLW's Exciting Adventures - Energy Expenditures in SPACE!

Counting Calories: The Problem, Approaches, and Best Calorie Counting Tool Ever Developed - Guessing with an equation. Online calorie calculators offer several equations (such as Harris-Benedict, Mifflin-St. Jeor, Katch-McArdle) that estimate energy expenditure based on your age, height, weight and sex. Unfortunately, many of us lie far off this estimate of the average person…sometimes by thousands of calories per day. https://images.squarespace-cdn.com/content/v1/63bdf003af127a1e397dafec/1685476239609-ZZ4D6GKFNOTI147YUSHW/image-asset.jpeg Blog - Counting Calories: The Problem, Approaches, and Best Calorie Counting Tool Ever Developed - Using a smartwatch or activity tracker. These add no more than 5% accuracy to the above estimates. At best, a smartwatch is 55% accurate. Simply put, your watch is lying to you! https://images.squarespace-cdn.com/content/v1/63bdf003af127a1e397dafec/1695419976336-M3KV4ZNQNWJ4EPBHOPEW/image-asset.jpeg Blog - Counting Calories: The Problem, Approaches, and Best Calorie Counting Tool Ever Developed - Living for days in a metabolic chamber. Welcome to food jail! This is the most accurate measurement of your metabolism. It works by measuring the amount of oxygen and CO2 entering an airtight room. This can only be done in an inpatient setting in a research study. While this measurement is extremely accurate, you are essentially a lab rat. You can’t eat your normal diet, do your normal exercise, or live your lifestyle. https://images.squarespace-cdn.com/content/v1/63bdf003af127a1e397dafec/1698271868634-WLBBFGMCYUIUTDQ80880/Calorify_r1_2387.jpg Blog - Counting Calories: The Problem, Approaches, and Best Calorie Counting Tool Ever Developed - The Calorify approach: Doubly labeled water . Let’s break down this revolutionary technique starting with the term itself: doubly labeled water. This is literally 100% water (H2O) where both (hence the ‘doubly’) oxygen and hydrogen atoms have been labeled. This is done by swapping the most common forms of oxygen and hydrogen with much rarer, but completely natural and safe, forms of oxygen and hydrogen. Specifically, they have a higher number of neutrons in their nucleus making them heavier than normal.
