Bioenergetics is the study of energy flow and transformation within living organisms, focusing on processes like cellular respiration and photosynthesis.
1st year Biology Chapter 11 Notes
The mechanism for ATP synthesis is: Chemiosmosis
When deprived of oxygen, yeast cells obtain energy by fermentation, producing carbon dioxide, ATP, and: Ethyl alcohol
Co-enzyme Q is in turn oxidized by cytochrome: b
In the first step of citric acid cycle, acetyl CoA reacts with oxaloacetate to form: Citrate
When a green plant performs photosynthesis at it maximum rate: The rate of water loss in high
Glycolysis: Reduces two molecules of NAD+For every glucose molecule processed
Glycolysis is the break down of: Glucose
Carbon fixation refers to the initial incorporation of: CO2
During the dark reaction of photosynthesis, the main process that occurs is: Adding of hydrogen to the carbon dioxide
Which statement about oxidative phosphorylation is not true: Its functions can be served equally well by fermentation
The power house of the cell is: Mitochondria
Magnesium is an important untrient ion in green plants as it is an essential component of: Chlorophyll
Which statement about ATP is not true: It is formed only under aerobic condition
Before pyruvate enters the citric acid cycle, it is decarboxylated, oxidized and combined with coenzyme A forming acetyl CoA, carbon dioxide and one molecule of: NADH
Which statement about the chemiosmotic mechanism is not true: Has no connection with the respiratory chain
The citric acid cycle: Takes place in the mitochondrion
Carbon dioxide enters the leaves through: Stomata
