Q

What is the form of energy that powers cellular work?

Q

How are ATP and ADP different

A

ATP stores energy and has 3 phosphate groups while ADP releases energy for the cells to use and has 2 phosphate groups

Q

Anaerobic respiration process

A

If the cell does not have any oxygen gas, it
will go through Glycolysis (but skip Kreb’s Cycle & Electron Transport Chain).

36 ATP
30
What is the final amount of ATP produced after breaking down one glucose molecule in anaerobic cellular respiration?
2 ATP
31
4 things are need for light-dependent reactions to occur
Light, NADP+, water, ADP
32
Label the image of the ATP
Adenine- ribose- 3 phosphate groups
33
What structure stores the most energy for cells to use
glucose
34
Name the substance that fills a chloroplast, the individual green balls, and a stack of the green balls

35
Photosynthesis occurs in two stages what are they?
Light-dependent reactions and the Calvin cycle (light-independent reactions)
36
What are the products of the Calvin cycle, and what time of day does it occur
Glucose, ADP, and NADP+ occurs during the day and nighttime
37
What is the first stage of light-dependent reactions and what time of day does it occur
