21
Q

it happens in the presence of light and it occurs in the thylakoid membrane and converts light energy into chemical energy. the energy harvested during stage is stored in a form of ATP and NADPH

A

Light independent reaction

22
Q

it is a light dependent reaction phase that takes place in the stroma and converts carbon dioxide into sugar or glucose. this stage does not directly need light but needs the product of the light reaction and it is occurs immediately after the light independent reaction

A

Calvin Cycle/light Dependent

24
Q

type of cellular respiration that A chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also called aerobic metabolism,cell respiration, and oxidative metabolism.,

A

Aerobic respiration

25
Q

The type of respiration through which cells can break down sugars to generate energy in the absence of oxygen

A

Anaerobic Respiration

26
Q

-the process in which glucose is broken down to produce energy. It makes two molecules of pyruvate, ATP, NADH, and water. The process occurs in a cell’s cytoplasm and does not require oxygen. It occurs in both aerobic and anaerobic organisms.
-the metabolic pathway that converts glucose into
pyruvate. Occurs in the cytosol and is oxygen-independent.

A

Glycolysis

27
Q

the end-product of glycolysis, derived from
additional sources in the cellular cytoplasm, and ultimately
destined for transport into mitochondria as a master fuel
input undergirding citric acid cycle carbon flux.

A

Pyruvate

28
Q

-is the main source of energy for cells and an important part of aerobic respiration.
- chain of reactions occurring in the mitochondria,
through which almost all living cells produce energy in aerobic respiration. It uses oxygen and gives out water and carbon dioxide as products.

A

krebs cycle or citric acid cycle

29
Q

the process by which ATP synthesis is coupled to the movement of electrons through the mitochondrial electron transport chain and the associated consumption of OXygen. It is also known as electron transport.

A

Oxidative phosphorylation

30
Q

energy is used to pump hydrogen ions across the mitochondrial inner membrane, from the matrix into the intermembrane space.

A

During Electron transport

31
Q

an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Examples of autotrophs include plants, algae, and some types of bacteria.

A

autotroph

32
Q

is an organism that eats other plants or animals for energy and nutrients. Dogs, birds, fish, and humans are all examples of heterotrophs.

A

heterotroph

33
Q

Which structure allows carbon dioxide to enter a plant system?

A

Stomata

34
Q

Which is the primary product of light-independent reactions?

A

Glucose

35
Q

Which of the following describes the process that releases energy by breaking
down food molecules in the presence of oxygen?

A

Cellular Respiration

36
Q

Product of Cellular Respiration

A

Water, Carbon Dioxide and Atp

37
Q

small molecules pass freely through the outer membrane it includes proteins called porins form channels that allow protein

A

Outer membrane

38
Q

these are the folds of the inner membrane

A
