Explanation / Answer
lactic acid (animals), ethanol and glycerol (yeast)
Fate is further aerobic oxidation.
Acetyl CoA
This can either enter TCA cycle or can be utilized for fatty acid synthesis.
oxaloacetate
Can be reused in TCA cycle or can be converted to glucose by gluconeogenesis.
Lipid catabolism
(fattyacid portion)
oligopeptides, dipeptides, aminoacids.
Aminoacids are reused for protein synthesis or enter gluconeogenesis
G3P is an intermediate.
In every cycle, 1 molecule is used for glucose synthesis while others are used for regeneration of RuBP.
Dihydroxy acetone phosphate
---------------------Ribulose bis phosphate (RuBP)
DHAP is one intermediate, 3 carbon compound in glycolysis
-----------------
DHAP on Complete oxidation produces 8 molecules of ATP in glycolysis-------------
DHAP finally produces lactic acid
-----------------
-----------------RuBP is the substrate for calvin cycle and

TCA cycle/ citric acid cycle/ kreb's cycle Acetyl CoA and oxaloacetateoxaloacetate
Can be reused in TCA cycle or can be converted to glucose by gluconeogenesis.
Electron transport chain NADH/ FADH2 / NADPH ATP utilized for energy andin several adenylation reactions Lipid catabolism (Glycerol portion) glycerol is freed by beta oxidation of triglyceride glycerol is utilized for fatty acid synthesisLipid catabolism
(fattyacid portion)
saturated and unsaturated fatty acids, phospholipids, all types of lipids acetyl CoA and other branched substances like phosphate residue, galactose from cerebroside, depending on the lipid catabolized Protein catabolism Proteinoligopeptides, dipeptides, aminoacids.
Aminoacids are reused for protein synthesis or enter gluconeogenesis
Photosynthesis (cyclic light dependent reactions) electron transport only in photosystem I ATP Photosynthesis (light dependent noncyclic reactions) electron transport in photosystem II and photosystem I 1 molecule of ATP and 1 molecule of NADPH per electron pair Photosynthesis, light independent reaction: Calvin cycle 3 ribulose 1,5-bis phosphate + 3 CO2 + 6ATP + 6NADPH 3ribulose 1,5- bis phosphate+ 1 glyceraldehyde 3 phosphate (this is converted to carbohydrate)
