Alcoholic fermentation regenerates the NAD+ needed for glycolysis to continue. It also produces CO2 and alcohol in the process. Fermentation Video Tutorial: youtu.be/quI_4VyUBKM #fermentation #glycolysis #biochemistry

The #coricycle allows for the recycling of #lacticacid. Lactate is sent to the liver, where it becomes pyruvate then glucose. However, this costs 6 ATP so it can't continue forever Fermentation Video Tutorial: youtu.be/quI_4VyUBKM #fermentation #respiration

It's #dnaday! Ever wonder how or where to draw the line between nature and nurture? Enter: #epigenetics! This field of study shows how nature AND nurture play a role Epigenetics: Nature vs. Nurture youtu.be/Q8BMP6HDIco via @YouTube #naturevsnurture #genetics

Lactic acid fermentation regenerates the NAD+ needed for glycolysis to continue. It also produces 2 molecules of lactic acid, but does NOT produce CO2! Fermentation Video Tutorial: youtu.be/quI_4VyUBKM #fermentation #glycolysis #biochemistry

Lactic Acid and Alcoholic #Fermentation occur in the cytoplasm. LAF gives us cheese, yogurt and kimchi, as well as the lovely burning when you exercise hard. AF gives us bread, wine, beer and more! Fermentation Video Tutorial: youtu.be/quI_4VyUBKM #lacticacid #respiration

There are two major types of fermentation; lactic acid and alcoholic. Both of them allow for the oxidation of NADH back into the NAD+ needed to run #glycolysis. Fermentation Video Tutorial: youtu.be/quI_4VyUBKM #lacticacid #fermentation #respiration

#Glycolysis breaks down glucose into pyruvate. The pyruvate can be used for #aerobicrespiration, #anaerobicrespiration, #lacticacidfermentation, or #alcoholicfermentation. Fermentation Video Tutorial: youtu.be/quI_4VyUBKM #lacticacid #fermentation #respiration

#Glycolysis has 2 phases; investment and payoff. In the investment phase, we spend 2 ATP to break up 1 glucose. In the payoff phase, we recharge 4 ATP, produce 2 NADH and 2 pyruvate. Fermentation Video Tutorial: youtu.be/quI_4VyUBKM #lacticacid #fermentation #respiration

#Photosynthesis explained! This diagram shows the Light Independent Reactions, aka the Calvin Cycle. Here, we use ATP and NADPH from the Light Dependent Reactions to "remix" carbon from CO2 into Glucose. Photosynthesis Video Tutorial: youtu.be/ZKC_aRrf1Rg #plants #grow

C3 C4 and CAM plant anatomy helps them perform their own type of photosynthesis. C4 and CAM plants are great at avoiding wasteful photorespiration; C4 uses bundle sheath cells and CAM splits it into a day and night process. C3 C4 CAM Plant Tutorial: youtu.be/P_JU9vYd5O0

Bumping CO2 from 340ppm to about 800-900 ppm gives photosynthesis a ~20% boost. Above that the curve flattens out. It should also be noted that letting CO2 levels dip BELOW 340 is more detrimental than boosting CO2 is beneficial. C3 C4 CAM Plant Tutorial: youtu.be/P_JU9vYd5O0

Temperature and CO2 supply tend to limit photosynthesis. At low temperatures, RuBisCO is less likely to function as quickly as needed, and at high temperatures membranes and enzymes tend to denature or fall apart. C3 C4 CAM Plant Tutorial: youtu.be/P_JU9vYd5O0

Wasteful Photorespiration increases in hot weather. Plants close their stomata to avoid drying out, preventing new CO2 from entering the leaf. RuBisCO has greater affinity for O2 at higher temps. Eventually, the CO2 will run out C3 C4 CAM Plant Tutorial: youtu.be/P_JU9vYd5O0

Plants need light, water and CO2 to perform photosynthesis. Optimizing the temperature and CO2 concentrations is crucial for maximum photosynthesis. With the right conditions, we reduce wasteful photorespiration. C3 C4 CAM Plant Tutorial: youtu.be/P_JU9vYd5O0
